Abstract:
Ni4Nb2O9 displays magnetization reversal, a particular behavior in which magnetization opposes an applied magnetic field. Previous studies have shown that this is caused by the antiferromagnetic coupling of two different layers of ferromagnetic Ni cations. In this work, magnetization reversal is controlled by the substitution of Ni by non-magnetic Zn. Ni4− xZn xNb2O9 materials with x = 0.25, 0.50, and 0.75 maintain the orthorhombic Ni4Nb2O9-type structure but display counterintuitive changes in the magnetic properties including increases in low-temperature net magnetizations, remnant magnetizations, and compensation temperatures. Furthermore, the magnetization reversal is significantly enhanced for x = 0.50 while supressed for x = 0.75, underscoring the strong effects of Zn substitution.

Abstract:
We have investigated the dynamical actuation of micro-electromechanical systems under the influence of attractive and repulsive Casimir forces between topological insulator plates as a function of their dielectric function and coating magnetization. The analysis of the Casimir force in the limit of strong and weak magnetization shows that the attractive force, which is produced for plate magnetizations in the same direction, is greater than the repulsive force that is produced for opposite magnetizations. However, both forces remain comparable for intermediate magnetizations. Moreover, for weak magnetization, the attractive force becomes stronger for an increasing dielectric function, while the opposite occurs for the repulsive force. On the other hand, increasing magnetization decreases the influence of the dielectric function on both the repulsive and attractive forces. Furthermore, for conservative systems, bifurcation and phase portrait analysis revealed that increasing magnetization decreases the regime of stable operation for devices with attractive forces, while their operation remains always stable under the presence of repulsive forces. Finally, for non-conservative periodically driven systems, the Melnikov function and Poincaré portrait analysis show that for magnetizations in the same direction leading to strong attractive Casimir forces, chaotic motion toward stiction is highly likely to occur preventing the long-term prediction of actuating dynamics. A remedy for this situation is obtained by the application of any magnetization in opposite directions between the interacting surfaces since the repulsive force makes it possible to prevent stiction.

Abstract:
The low temperature magnetizations of TbGG have been systematically investigated from the average effect of the nonequivalent crystal sites. Our calculated results show that the different nonequivalent crystal sites have the different contributions to the magnetization. The step-like appearance of the low temperature magnetization curves in TbGG originates from the average effect of the magnetizations of six nonequivalent crystal sites, not from the near-crossing of the lowest energy levels of Tb3+ions.

Abstract:
In GdFeCo/Ir/GdFeCo heterostructures with amorphous GdFeCo layers, three critical points were found in the temperature dependences of the magnetization. In the neighborhood of 100 K, the temperature of compensation for the magnetizations of the Gd and FeCo sublattices is observed, which is found in the form of a magnetization minimum and does not depend on the magnetic field. As the temperature decreases, a sharp stepwise transition is observed, which corresponds to the switching of the mutual magnetization’s orientation of the GdFeCo layers between their parallel and antiparallel configurations. This transition depends on the magnetic field in which the measurement is made. Its critical temperature shifts in the range of 70–300 K with a change in the field in the range of 0.5–5 T. At low temperatures < 50 K, a transition to the spin glass state is observed, which is accompanied by a decrease in the magnetic moment to zero and disappears when the field is applied.

Abstract The magnetization process of the S = 1 antiferromagnetic chain with the single-ion anisotropy D and the biquadratic interaction is investigated using the numerical diagonalization. Both interactions stabilize the 2-magnon Tomonaga-Luttinger liquid (TLL) phase in the magnetization process. Based on several excitation gaps calculated by the numerical diagonalization, some phase diagrams of the magnetization process are presented. These phase diagrams reveal that the spin nematic dominant TLL phase appears at higher magnetizations for sufficiently large negative D.

Full text
Abstract:
We study inverse potential problems with source term the divergence of some unknown (ℝ3-valued) measure supported in a plane; e.g., inverse magnetization problems for thin plates. We investigate methods for recovering a magnetization μ by penalizing the measure-theoretic total variation norm ∥μ∥TV , and appealing to the decomposition of divergence-free measures in the plane as superpositions of unit tangent vector fields on rectifiable Jordan curves. In particular, we prove for magnetizations supported in a plane that TV -regularization schemes always have a unique minimizer, even in the presence of noise. It is further shown that TV -norm minimization (among magnetizations generating the same field) uniquely recovers planar magnetizations in the following two cases: (i) when the magnetization is carried by a collection of sufficiently separated line segments and a set that is purely 1-unrectifiable; (ii) when a superset of the support is tree-like. We note that such magnetizations can be recovered via TV -regularization schemes in the zero noise limit by taking the regularization parameter to zero. This suggests definitions of sparsity in the present infinite dimensional context, that generate results akin to compressed sensing.

Full text
Abstract:
In the Athabasca Basin, diagenetic hematite of variable paragenesis occurs throughout the sandstones and underlying paleoregolith. This hematite carries three distinct, single-component magnetizations: A (D = 158°, I = 62°, α95 = 5°, n = 21); B (D = 11°, I = −36°, α95 = 7°, n = 6); and C (D = 18°, I = 79°, α95 = 3°, n = 27). In some areas of the sandstones, such as near reactivated fault zones, the diagenetic hematite has been altered to goethite which yields a very low-intensity, incoherent D magnetization. Ages for the A, B, and C magnetizations, inferred from comparisons with paleomagnetic directions in Precambrian rocks whose ages are known approximately, are 1750–1600, 1600–1450, and about 900 Ma, respectively. The A magnetization is carried by the earliest formed hematite, and its estimated age compares well with U–Pb ages of 1650–1700 Ma for early diagenetic apatite. U–Pb and Rb–Sr ages of approximately 1500 and 900 Ma for uraninite and illite coeval with hematite that carries the B and C magnetizations compare well with their ages estimated from paleomagnetism. The development of B magnetization appears to be coeval with high-grade, unconformity-type uranium mineralization.Petrographic and field relationships indicate that the A magnetization is carried by hematite formed during initial diagenesis of the Athabasca sandstones, the B magnetization is carried by hematite formed during peak diagenesis, and the C magnetization is carried by hematite formed during subsequent high-temperature hydrothermal alteration. The incoherent D magnetizations have resulted from degradation of hematite to goethite as a result of incursion of low-temperature meteoric waters along fault zones that have been continuously reactivated since the late Precambrian. δ18O values of clay minerals and of the coeval hematite which carries the B and C magnetization indicate that they were formed from a fluid having temperatures of 150–200 °C and δ18O values near 1.0‰. Fluids that deposited the early formed hematite carrying the A magnetism are relatively 18O depleted, with values of approximately 0.8‰ and somewhat lower temperatures of 120–160 °C. Intermingling of A, B, and C magnetizations indicates either that hematite may be deposited by one fluid and reprecipitated by a subsequent fluid, or that fluid flow was controlled by local variations in permeability. Evidently, fluid flow has been episodic and basin wide and has occurred over a time span on the order of 108 years. It is suggested that the stratigraphy of the sandstones controlled the basin-wide lateral migration of the basinal fluids and that faults facilitated interformational fluid flow.

This paper investigates both static and dynamic eccentricities in single phase brushless DC (BLDC) motors and analyzes the effect of the PM magnetization field on unbalanced magnetic forces acting on the rotor. Three common types of PM magnetization field patterns including radial, parallel and sinusoidal magnetizations are considered. In both static and dynamic eccentricities, harmonic components of the unbalanced magnetic forces on the rotor are extracted and analyzed. Based on simulation results, the magnetization fields that produce the lowest and highest unbalanced magnetic forces are determined in rotor eccentricity conditions.

Full text
Abstract:
The concept of equivalent sources is described from first principles. Two types of sources that produce the same magnetic field are studied in detail: thin sheets and uniaxially magnetized half‐spaces. Simple analytic solutions show that their magnetization variations are essentially given by the pseudogravity field and the magnetic field, respectively. While the former varies slowly to account for the slow variation in the vertically integrated magnetization, the latter varies rapidly to account for the spatial variation in rock magnetization close to the observation points. An extension of these simple distributions is the sandwich distribution. Using statistical arguments, we construct sandwich distributions. The depths and mean magnetizations of each layer are found from the decay of the azimuthally averaged power spectrum. The equivalent layer magnetizations closely resemble the magnetic field anomaly when upward‐continued to a height equal to the mean depth of the layer.

Abstract:
The area of ultrafast (sub-nanosecond) magnetization dynamics of ferromagnetic elements and thin films, usually driven by a strong femtosecond laser pulse, has experienced intense research interest. In this dissertation, laser-induced demagnetization is theoretically studied by taking into account interactions among electrons, spins, and lattice. We propose a microscopic approach under the three temperature framework and derive the equations that govern the demagnetization at arbitrary temperatures.To address the question of magnetization reversal at high temperatures, the conventional Landau-Lifshitz equation is obviously unsatisfactory, since it fails to describe the longitudinal relaxation. So by using the equation of motion for the quantum density matrix within the instantaneous local relaxation time approximation, we propose an effective equation that is capable of addressing magnetization dynamics for a wide range of temperatures. The longitudinal and transverse relaxations are analyzed, magnetization reversal processes near Curie temperatures is also studied. Furthermore, we compared our derived Self-consistent Bloch equation and Landau-Lifshitz-Bloch equation in detail. Finally, the demagnetzation dynamics for ferromagnetic and ferrimagnetic alloys is studied by solving the Self-consistent Bloch equation.

Abstract:
Abstract This thesis reports simulations of direct observables in electron and nuclear spin relaxation experiments in an example paramagnetic system, as well as polarization transfer occurring in a spin-exchange optical pumping (SEOP) experiment. Studies of paramagnetic relaxation are important, e.g., in the development of agents used for enhanced contrast in magnetic resonance imaging. SEOP is used to produce hyperpolarized noble gases, which are then used to, e.g., enhance sensitivity in structural studies of matter with nuclear magnetic resonance. Presently the theory, available software and hardware for such computational modeling have reached a state in which quantitative reproduction of the experimentally observed magnetization decay is possible from first principles. The present multiscale computations are carried out from first principles combining molecular dynamics simulations of atomistic motion and quantum-chemical electronic structure calculations of the spin interaction parameters that enter the effective spin Hamiltonian. A time series of the spin Hamiltonian is then explicitly used to propagate spin dynamics in the system, and dynamical time constants of the magnetization are obtained through ensemble averaging. The complete decay of electron spin magnetization could be followed directly within the duration of the simulation, whereas the nuclear spin relaxation rates were extracted using Kubo’s theory regarding generalized cumulant expansion and stochastic processes. The extracted electron and nuclear spin relaxation rates for the chosen prototypic system, the aqueous solution of Ni²⁺, are in quantitative and semi-quantitative agreement, respectively, with the available experimental results. The simulations of polarization transfer corroborate the empirical observations on the importance of van der Waals complexes and binary collisions in the spin-exchange process. Long van der Waals complexes represent the overwhelmingly most significant kind of individual events, but the short binary collisions can also give a relatively important contribution due to their vast abundance. This thesis represents a first study in which first principles-calculated trajectories of individual events could be followed. The simulations reported in this thesis were run without any empirical parametrization and thus represent a significant step in first-principles computational modeling of magnetization dynamics.

Abstract:
Simulations on magnetization dynamics are of great interest on current research. Unlike computational fluid dynamics, magnetization dynamics has not received much attention from the visualization community. In this work a design and preliminary implementation of a visualization tool for magnetization dynamics simulations is introduced, based on methods used in the literature of the field. Although immature, the introduced design and implementation provide some advantages over some tools in use, and further development could lead to a unified and complete visualization utility.

Abstract:
In the thesis at hand, different concepts of magnetic recording were investigated both from an experimental and theoretical point of view. On the one hand, micromagnetic simulations of bit patterned media were performed examining the influence of magnetic and geometrical parameters on the magnetization reversal mechanism of the bit array. In this regard, the recording concept called exchange coupled composite (ECC) media was applied in combination with bit patterned media (BPM). It was demonstrated that ECC/BPM is superior in terms of narrowing the SFD which is vital for the implementation of BPM as a recording scheme in magnetic data storage deviced. Moreover, the stability of the magnetic state was calculated for single nanomagnets using the nudged elastic band algorithm. It was found out that the magnetic and geometrical properties have a severe influence on both, the energy barrier for magnetization reversal and the magnetization reversal process of the single nanomagnets. On the other hand, experimental studies of granular CoCrPt:SiO2 films deposited on self-assembled arrays of SiO2 nanoparticles with a size from 10 nm to 330 nm have been carried out, showing a distinct size-dependence of the coercive field and remanent magnetization with changing nanoparticle size. Moreover, these films have been irradiated with Co+ ions with different fluences, resulting in a change of the magnetic properties of the films due to both a change of the intergranular exchange coupling of the film and a degredation of the magnetic layers at higher irradiation fluences.

Abstract:

A 2014 study by the US Department of Energy conducted at Lawrence Berkeley National Laboratory estimated that U.S. data centers consumed 70 billion kWh of electricity. This represents about 1.8% of the total U.S. electricity consumption. Putting this in perspective 70 billion kWh of electricity is the equivalent of roughly 8 big nuclear reactors, or around double the nation's solar panel output. Developing new memory technologies capable of reducing this power consumption would be greatly beneficial as our demand for connectivity increases in the future. One newly emerging candidate for an information carrier in low power memory devices is the magnetic skyrmion. This magnetic texture is characterized by its specific non-trivial topology, giving it particle-like characteristics. Recent experimental work has shown that these skyrmions can be stabilized at room temperature and moved with extremely low electrical current densities. This rapidly developing field requires new measurement techniques capable of determining the topology of these textures at greater speed than previous approaches. In this dissertation, I give a brief introduction to the magnetic structures found in Fe/Gd multilayered systems. I then present newly developed techniques that streamline the analysis of Lorentz Transmission Electron Microscopy (LTEM) data. These techniques are then applied to further the understanding of the magnetic properties of these Fe/Gd based multilayered systems.

Full text
Abstract:
Magnetization transfer (MT) imaging is a magnetic resonance imaging techniqu ewhich permits indirect observation of the macromolecular component of biological tissue. Semi-quantitative implementations such as magnetization transfer ratio (MTR) imaging are very useful in the study of neuro-degenerative diseases, despite the relatively limited information provided by such single measurement methods. Quantitative techniques provide estimated measures of model parameters that more accurately describe the MT process. This thesis presents the application of quantitative MT imaging in a cross-sectional study of multiple sclerosis (MS) patients and healthy controls, exploring the on-going changes that occur in MS. Quantitative results are investigated to determine which model parameters play a role in the MTR. The findings demonstrate regional variations in white matter structures, and significant differences between healthy and normal-appearing MS tissue. The results also indicate the dominant role of macromolecular content in MTR, and confirm the destructive nature of T 1-hypointense lesions.

Abstract:
Ferromagnetic pipeline steel may exhibit magnetization, even in the absence of applied magnetic fields, due to remnant fields or the presence of pipe wall stress. Remnant magnetization may be present from previous or existing exposure to a magnetic field, while pipe wall stress induced magnetization can result from line pressure, environmental stresses due to settling or geohazard conditions, and residual stresses due to nonuniform plastic deformation caused by manufacturing processes, installation or operating conditions. The local stress state of the pipeline may also be altered by corrosion or damage. The physical basis for magnetization in pipelines due to intrinsic and resident stresses is examined here using the magnetic object (MO) model. MOs are characterized as regions of relatively independent magnetic behaviour, typically about the size of a ferromagnetic steel grain, to which expressions for the magnetic energy of local domain structures can be applied. The lowest energy state for an MO is a flux-closed structure, but the presence of stress can modify the MO energy through inverse magnetostrictive effects on the domain structure and thereby, produce a state of magnetization. This magnetization may be altered by the introduction of additional stress sources including pressurization of the pipe, geological-environment effects, sources of magnetization that include the proximity of other ferromagnetic pipes, even those comprising sections of the same pipeline, and changes in the pipe structure that may be brought about by deformation, corrosion or cracking. This work shows that the fundamental building block of the MO, combined with considerations of overall changes in domain structure due to these factors, can be used to model the generation of magnetic fields measured outside of pipeline structures. This will have implications for understanding sources of pipeline magnetization that are passively measured above buried oil and gas pipelines with the objective of detecting anomalous conditions that may indicate compromised conditions for safe pipeline operation.

Abstract:
Magnetic flux leakage (MFL) is the most commonly used in-line inspection method for pipelines and will most likely remain the preferred technology for many decades. However, MFL does have its limitations on sizing corrosion anomalies. This work investigates an enhanced MFL implementation to improve assessment of corrosion anomalies. This implementation uses signals recorded at two magnetization levels: high levels typical of modern commercial MFL tools and low levels near the knee of the nonlinear magnetization curve. A method for combining signals from both field levels was developed, which can detect plastic deformation stresses on smaller defects and define sharp geometry changes of larger defects. This method was tested on 21 corrosion anomalies with mixed results. Some unique information about stress at long, narrow corrosion anomalies was obtained from the two magnetization level signals. Unfortunately, an unexpected nonlinear geometry signal was also present in many of the corrosion anomalies that obscured the stress signal, limiting the general application of this technique to narrow anomalies.
