Abstract:
Magneto-transport and magnetic data on MgB 2 polycrystalline samples are reported for applied magnetic fields up to 9 T. In the normal state we find that MgB 2 compound has a temperature and field-dependent resistivity behavior like a simple metal. The critical magnetic field Hc2(T) and the irreversibility field Hirr(T) curves were determined. The Hall coefficient RH is slightly temperature dependent. Using the extracted data, we calculated the electronic mean free path, coherency length ξ0 and London penetration depth λL.

Magnetic composites, obtained on associating magnetic fluid with non-magnetic particles, offer interesting opportunities in separations, assemblies and other applications, where the microstructure of the composite can be altered reversibly by an external field without altering the composition. The goal of our work in this area is to develop computational and simulation tools to assist in the in-depth understanding of the thermodynamic and transport properties of such non-magnetic nanoparticles immersed in magnetic fluids under varying magnetic field conditions. Also, in this work we have studied the relaxation and magnetization characteristics of magnetic nanoparticle clusters in presence of low external magnetic fields. Theoretical analysis of such a complex system is difficult using conventional theories, and hence we have used Monte Carlo Simulations to explore these effects. We simulated the interactions between non-magnetic particles (1000 nm) and magnetic nanoparticles (10 nm and 20 nm diameter) dispersed in organic phase. We observed that the presence of the non-magnetic particle in the system induces magnetic non-homogeneity. The magnetic nanoparticles present in the equatorial place of the non-magnetic particle with reference to the applied magnetic field have a higher magnetization as compared to the particles in the polar region. This effect was much more dominant for 20 nm particles than 10nm particles, because the magnetic inter-particle interactions are much stronger for the larger particles. We have also studied the effect of radial distance from the nonmagnetic particle on the magnetization and radial distribution function characteristics of the magnetic nanoparticles.
(cont.) We have evaluated the magnetophoretic forces the non-magnetic particles experience when subjected to magnetic field gradient. We have identified such forces arising from the inter-particle interactions between the magnetic nanoparticles. These forces were found to be significant for larger magnetic particles, smaller non-magnetic particles and lower magnetic fields. Diffusion coefficients were evaluated for non-magnetic nanoparticles in magnetic fluids using Brownian Dynamics Simulation. The chain-like structures formed by magnetic nanoparticles introduce anisotropy in the system with the diffusion coefficients higher along the direction of applied external magnetic field and lower in the perpendicular direction. It was observed that the anisotropy increases with higher magnetic particle concentration and larger non-magnetic particles. Anisotropy is negligible for small sized magnetic particles for which the inter-particle interaction is smaller, increases with increasing magnetic particle size and becomes constant thereafter. Results were compared with theoretical predictions. Néel Relaxation was studied for magnetic nanoparticle clusters. Chain-like, spherical and planar clusters were evaluated for the relaxation times. For chain-like structures the relaxation times increase significantly on increasing the chain length and particle size. For spherical clusters the relaxation times were fairly similar to that of individual magnetic nanoparticles. Hence, such a fast relaxation makes them ideal candidates for HGMS separations, since they will be released quickly from the magnetic wires during the elution step.
(cont.) Also, we studied the magnetization characteristics of rectangular and hexagonal packing arrangements of magnetic clusters in presence of remnant fields. The hexagonal arrangement revealed a novel oscillatory behavior. A theoretical model was developed to predict the magnetic particle size beyond which the oscillations are observed.

Abstract:
The present thesis is about the investigation of ferromagnetic thin film systems with respect to exchange coupling, magnetization reversal behavior and effects appearing in magnetic heterostructures, namely the exchange bias and the giant magnetoresistance effect. For this purpose, DC magnetron sputtered thin films and multilayers with perpendicular magnetic anisotropy were prepared on single crystalline and rigid as well as flexible amorphous substrates. The first part concentrates on magnetic data storage applications based on the combination of the concept of bit patterned media and three dimensional magnetic memory, consisting of at least two exchange decoupled ferromagnetic storage layers. Here, [Co/Pt] multilayers, revealing different magnetic anisotropies, have been applied as storage layers and as spacer material Pt and Ru was employed. By the characterization of the magnetization reversal behavior the exchange coupling in dependence of the spacer layer thickness was studied. Furthermore, with regard to the concept of bit patterned media, the layers were also grown on self-assembled silica particles, leading to an exchange decoupled single-domain magnetic dot array, which was studied by magnetic force microscope imaging and angular dependent magneto-optic Kerr effect magnetometry to evaluate the reversal mechanism and its dependence on the array dimensions, mainly the diameter of the silica particles and layer thicknesses. To complete the study, micromagnetic simulations were performed to access smaller dimensions and to investigate the dependence of intralayer as well as interlayer coupling on the magnetization reversal of the dot array with multiple storage layers. The second part focuses on the investigation of the giant magnetoresistance effect in systems with perpendicular magnetic anisotropy, where L10 -chemically ordered FePt alloys and [Co/Pt] as well as [Co/Pd] multilayers were utilized. In case of FePt, where high temperatures during the deposition are necessary to induce the chemical ordering, diffusion and alloying of the spacer material often prevent a sufficient exchange decoupling of the ferromagnetic layers. However, with Ru as spacer material a giant magnetoresistance effect could be achieved. Large improvements of the magnetoresistive behavior of such trilayer structures are presented for [Co/Pt] and [Co/Pd] multilayers, which can be deposited at room temperature not limiting the choice of spacer as well as substrate material. Furthermore, in systems consisting of one ferromagnet with perpendicular magnetic anisotropy and one ferromagnet with in-plane magnetic easy axis, a linear and almost hysteresis-free field dependence of the electrical resistance was observed and the behavior for various thickness series has been intensively studied. Finally, the corrosion resistance in dependence of the capping layer material as well as the magnetoresistance of a strained flexible pseudo-spin-valve structure is presented. In addition, in chapter 2.5.2 an experimental study of an improved crystal growth of FePt at comparable low temperatures by molecular beam epitaxy and further promoted by a surfactant mediated growth using Sb is shown. Auger electron spectroscopy as well as Rutherford backscattering spectrometry were carried out to confirm the surface segregation of Sb and magnetic characterization revealed an increase of magnetic anisotropy in comparison to reference layers without Sb

Die Probenpräparation erfolgte mittels DC Magnetronsputtern, wobei auf einkristallinen aber auch flexiblen sowie starren amorphen Substraten abgeschieden wurde. Im ersten Teil der Arbeit werden Untersuchungen mit dem Hintergrund einer Anwendung als magnetischer Datenträger vorgestellt. Konkret werden hier die Konzepte Bit Patterned Media (BPM) und 3D Speicher miteinander kombiniert. Letzteres Konzept basiert auf der Verwendung wenigstens zweier austauschentkoppelter ferromagnetischer Schichten, für welche [Co/Pt] Multilagen mit unterschiedlicher magnetischer Anisotropie verwendet wurden. Als Zwischenschichtmaterial diente Pt und Ru. Durch die Charakterisierung des Ummagnetisierungsverhaltens wurde die Austauschkopplung in Abhängigkeit der Zwischenschichtdicke untersucht. Darüber hinaus wurden jene Schichtstapel zur Realisierung des BPM-Konzeptes auf selbstangeordnete SiO2 Partikel mit unterschiedlichen Durchmessern aufgebracht, durch welche sich lateral austauschentkoppelte, eindomänige magnetische Nanostrukturen erzeugen lassen. Zur Untersuchung des Ummagnetisierungsverhaltens und der jeweiligen Größenabhängigkeiten (maßgeblich Durchmesser und Schichtdicke) wurden diese mittels Magnetkraftmikroskopie sowie winkelabhängiger magnetooptischer Kerr Effekt Magnetometrie untersucht. Zur weiteren Vertiefung des Verständnisses noch kleinerer Strukturgrößen erfolgten mikromagnetische Simulationen, bei denen die magnetischen Wechselwirkungen lateral (benachbarte 3D Elemente) als auch vertikal (Wechselwirkungen ferromagnetischer Schichten innerhalb eines 3D Elementes) im Interesse standen, sowie deren Auswirkungen auf das Ummagnetisierungsverhalten des gesamten Feldes. Der Fokus des zweiten Teils liegt auf der Untersuchung des Riesenmagnetwiderstandseffektes in Systemen mit senkrechter Sensitivität. Dafür sind ferromagnetische Schichten mit senkrechter magnetischer Anisotropie nötig, wobei hier die chemisch geordnete L10-Phase der FePt Legierung und [Co/Pt] sowie [Co/Pd] Multilagen Anwendung fanden. Für eine chemische Ordnung der FePt Legierung sind hohe Temperaturen während der Schichtabscheidung notwendig, welche eine hinreichende Austauschentkopplung beider ferromagnetischer Schichten meist nicht gewährleisten. Grund dafür sind einsetzende Diffusionsprozesse als auch Legierungsbildungen mit dem Zwischenschichtmaterial. In der vorliegenden Arbeit konnte der GMR Effekt daher ausschließlich mit einer Ru Zwischenschicht in FePt basierten Trilagensystemen nachgewiesen und charakterisiert werden. Enorme Verbesserungen der magnetoresistiven Eigenschaften werden im Anschluss für [Co/Pt] und vor allem [Co/Pd] Multilagen vorgestellt. Diese Schichtsysteme mit senkrechter magnetischer Anisotropie können bei Raumtemperatur präpariert werden und stellen daher keine weiteren Anforderungen an das Zwischenschichtmaterial sowie die verwendeten Substrate. Hier wurden neben Systemen mit ausschließlich senkrechter magnetischer Anisotropie auch Systeme mit gekreuzten magnetischen Anisotropien intensiv untersucht, da diese durch einen linearen und weitgehend hysteresefreien R(H) Verlauf imHinblick auf Sensoranwendungen enorme Vorteile bieten. Letztendlich wurde die Korrosionsbeständigkeit in Abhängigkeit des Deckschichtmaterials als auch die mechanische Belastbarkeit von auf flexiblen Substraten abgeschiedenen GMR-Schichtstapeln untersucht. Zusätzlich wird in Kapitel 2.5.2 eine experimentelle Studie zum Surfactant-gesteuerten Wachstum der FePt Legierung mittels Molekularstrahlepitaxie vorgestellt. Als Surfactant dient Sb, wodurch die Kristallinität bei geringer Depositionstemperatur deutlich verbessert werden konnte. Die Oberflächensegregation von Sb wurde mittels Auger Elektronenspektroskopie und Rutherford Rückstreuspektrometrie verifiziert und die Charakterisierung magnetischer Eigenschaften belegt einen Anstieg der magnetischen Anisotropieenergie im Vergleich zu Referenzproben ohne Sb

Abstract:
My dissertation research focuses on the investigation of the transport and magnetic properties of transition metal and rare earth doped oxides, particularly SnO2 and HfO2 thin films. Cr- and Fe-doped SnO2 films were deposited on Al2O3 substrates by pulsed-laser deposition. Xray- diffraction patterns (XRD) show that the films have rutile structure and grow epitaxially along the (101) plane. The diffraction peaks of Cr-doped samples exhibit a systematic shift toward higher angles with increasing Cr concentration. This indicates that Cr dissolves in SnO2. On the other hand, there is no obvious shift of the diffraction peaks of the Fe-doped samples. The magnetization curves indicate that the Cr-doped SnO2 films are paramagnetic at 300 and 5 K. The Fe-doped SnO2 samples exhibit ferromagnetic behaviour at 300 and 5 K. Zero-field-cooled and field-cooled curves indicate super paramagnetic behavior above the blocking temperature of 100 K, suggesting that it is possible that there are ferromagnetic particles in the Fe-doped films. It was found that a Sn0.98Cr0.02O2 film became ferromagnetic at room temperature after annealing in H2. We have calculated the activation energy and found it decreasing with the annealing, which is explained by the increased oxygen vacancies/defects due to the H2 treatment of the films. The ferromagnetism may be associated with the presence of oxygen vacancies although AMR was not observed in the samples. Pure HfO2 and Gd-doped HfO2 thin films have been grown on different single crystal substrates by pulsed laser deposition. XRD patterns show that the pure HfO2 thin films are of single monoclinic phase. Gd-doped HfO2 films have the same XRD patterns except that their diffraction peaks have a shift toward lower angles, which indicates that Gd dissolves in HfO2. Transmission electron microscopy images show a columnar growth of the films. Very weak ferromagnetism is observed in pure and Gd-doped HfO2 films on different substrates at 300 and 5 K, which is attributed to either impure target materials or signals from the substrates. The magnetic properties do not change significantly with post deposition annealing of the HfO2 films.

Abstract:
This thesis explores the mechanisms of the magnetic reversal of permalloy artificial spin ice arrays. The main research foci include the influence of domain wall propagation on the magnetic reversal of honeycomb artificial spin ice, the low temperature behaviour of honeycomb artificial spin ice and the classification of inverse permalloy opals as three dimensional artificial spin ice. Room temperature imaging of the magnetisation configuration of the nanobars through the magnetic reversal, via scanning transmission X-ray microscopy, photoemission electron microscopy and Lorentz transmission electron microscopy, showed non random domain wall propagation through the frustrated vertices of the honeycomb artificial spin ice arrays. OOMMF simulations suggest that the origin of such non-randomness lies in the domain wall chirality. Boundary conditions necessary for domain wall injection into artificial spin ice arrays were investigated. A reduction of the edge nanobars width of 2/3 was needed to prevent random domain wall nucleation from the array edges. Electrical transport measurements showed evidence of a change in the magnetic reversal, driven by domain wall propagation, of honeycomb permalloy artificial spin ice below 15 K. The transition temperature was found to be proportional to the square of the saturation magnetisation of the ferromagnetic material used. The change in the magnetic reversal was associated with the non-random vertex domain wall positioning below the transition temperature due to the influence of vertex dipole interactions. Room temperature Lorentz transmission electron microscopy images and temperature dependent electrical transport measurements of three dimensional permalloy inverse opals showed the potential of magnetic inverse opals to act as three dimensional artificial spin ice systems.
