Résumé :

For the first time the current volume brings together a fully annotated edition of Hannah Lynch’s articles on Spain – many of which are devoted to travel – together with a critical study of her connections with the country. Lynch, a cosmopolitan New Woman, viewed Spain with ambivalence, impatient of its resistance to change yet seduced by its landscapes and peoples. Her writing, revealing of her commitment to women’s emancipation, warrants attention from those wishing to further explore women’s contributions to the cultural and literary relations between Ireland and the Iberian Peninsula.

Résumé :

Since the discovery of the giant magnetoresistance effect in magnetic multilayers in 1988, a new branch of physics and technology, called spin-electronics or spintronics, has emerged, where the flow of electrical charge as well as the flow of electron spin, the so-called “spin current,” are manipulated and controlled together. The physics of magnetism and the application of spin current have progressed in tandem with the nanofabrication technology of magnets and the engineering of interfaces and thin films. This book aims to provide an introduction and guide to the new physics and applications of spin current, with an emphasis on the interaction between spin and charge currents in magnetic nanostructures.

Résumé :

This chapter discusses the interaction between currents and magnetization, which can cause undesirable effects such as enhanced magnetic noise in read heads made from magnetic multilayers. While most research has been carried out on metallic structures, current-induced magnetization dynamics in semiconductors or even insulators has been pursued as well. These issues have attracted many physicists because, on top of the practical aspects, the underlying phenomena are fascinating. Berger and Slonczewski are acknowledged to have started the field in general through their introduction of the concept of current-induced magnetization dynamics by the transfer of spin. The reciprocal effect, i.e., spin pumping, was expected long ago, but it took some time before Tserkovnyak et al. developed a rigorous theory of spin pumping for magnetic multilayers, including the associated increased magnetization damping.

Texte intégral

Résumé :

This chapter discusses another type of equilibrium-spin current similar to the exchange-spin current—the topological spin current. Topological spin currents are driven by topological-band structure and classified into bulk and surface topological spin currents. The former is confined onto electron-band manifolds, sometimes affecting their motions. This confinement is addressed through the standard method of combining the equations of motion and the Boltzmann equation for semi-classical electrons in a band. The latter class, on the other hand, is a surface-spin current, which is limited near surfaces of a three-dimensional system and flows along these surfaces. This type is known to appear in topological insulators, where the bulk is insulating but the surface or edge is electrically conducting due to the surface or edge state.

Résumé :

This article examines spin currents and spin densities in realistic open semiconductor nanostructures using different tools of quantum-transport theory based on the non-equilibrium Green function (NEGF) approach. It begins with an introduction to the essential theoretical formalism and practical computational techniques before explaining what pure spin current is and how pure spin currents can be generated and detected. It then considers the spin-Hall effect (SHE), and especially the mesoscopic SHE, along with spin-orbit couplings in low-dimensional semiconductors. It also describes spin-current operator, spindensity, and spin accumulation in the presence of intrinsic spin-orbit couplings, as well as the NEGF approach to spin transport in multiterminal spin-orbit-coupled nanostructures. The article concludes by reviewing formal developments with examples drawn from the field of the mesoscopic SHE in low-dimensional spin-orbit-coupled semiconductor nanostructures.

Texte intégral

Résumé :

This chapter discusses the spin Hall effect that occurs during spin injection from a ferromagnet to a nonmagnetic conductor in nanostructured devices. This provides a new opportunity for investigating AHE in nonmagnetic conductors. In ferromagnetic materials, the electrical current is carried by up-spin and downspin electrons, with the flow of up-spin electrons being slightly deflected in a transverse direction while that of down-spin electrons being deflected in the opposite direction; this results in an electron flow in the direction perpendicular to both the applied electric field and the magnetization directions. Since up-spin and downspin electrons are strongly imbalanced in ferromagnets, both spin and charge currents are generated in the transverse direction by AHE, the latter of which are observed as the electrical Hall voltage.

Résumé :

This chapter describes an experiment on the inverse spin Hall effect (ISHE) induced by spin pumping. Spin pumping is the generation of spin currents as a result of magnetization M(t) precession; in a ferromagnetic/paramagnetic bilayer system, a conduction-electron spin current is pumped out of the ferromagnetic layer into the paramagnetic conduction layer in a ferromagnetic resonance condition. The sample used in the experiment is a Ni81Fe19/Pt bilayer film comprising a 10-nm-thick ferromagnetic Ni81Fe19layer and a 10-nm-thick paramagnetic Pt layer. For the measurement, the sample system is placed near the centre of a TE011 microwave cavity at which the magnetic-field component of the microwave mode is maximized while the electric-field component is minimized.

This article focuses on spintronics with metallic nanowires. It begins with a review of the highlights of spintronics research, paying attention to the very important developments accomplished with tunnel junctions. It then considers the effect of current on magnetization before discussing spin diffusion and especially spin-dependent conductivities, spin-diffusion lengths, and spin accumulation. It also examines models for spin-polarized currents acting on magnetization, current-induced magnetization switching, and current-driven magnetic excitations. It concludes with an overview of resonant-current excitations, with emphasis on spin-valves and tunnel junctions as well as resonant excitation of spin-waves, domain walls and vortices. In addition, the article reflects on the future of spintronics, citing in particular the potential of the spin Hall effect as the method of generating spin accumulation, free of charge accumulation.

Texte intégral

Résumé :

This chapter introduces the concept of exchange spin current, which derives from rewriting the exchange interaction in magnets and formulating a spin-wave spin current. States of matter can be classified into several types in terms of magnetic properties. In paramagnetic and diamagnetic states, matter has no magnetic order and exhibits zero magnetization in the absence of external magnetic fields. In ferromagnetic states, the permanent magnetic moments of atoms or ions align parallel to a certain direction, and the matter exhibits finite magnetization even in the absence of external magnetic fields. In ferrimagnets, the moments align antiparallel but the cancellation is not perfect and net magnetization appears. This interaction that aligns spins is called the exchange interaction.

Résumé :

This chapter introduces the concept of incoherent spin current. A diffusive spin current can be driven by spatial inhomogeneous spin density. Such spin flow is formulated using the spin diffusion equation with spin-dependent electrochemical potential. The chapter also proposes a solution to the problem known as the conductivity mismatch problem of spin injection into a semiconductor. A way to overcome the problem is by using a ferromagnetic semiconductor as a spin source; another is to insert a spin-dependent interface resistance at a metal–semiconductor interface.

Résumé :

Systems with spin-orbit coupling and magnetic fields exhibit a SU(2) structure. Large classes of materials and couplings can be written into an effective spin-orbit coupled Hamiltonian with Pauli structure. Appropriate kinetic equations are derived keeping the quantum spinor structure. It results in coupled kinetic equations of scalar and vector distributions. The spin-orbit coupling, the magnetic field and the vector part of the selfenergy can be written in terms of an effective Zeeman field which couples both distributions. The currents and linear response are derived and the anomalous parts due to the coupling of the occurring band splitting are discussed. The response in magnetic fields reveals subtle retardation effects from which the classical and quantum Hall effect result as well as anomalous Hall effects. As application the dynamical conductivity of grapheme is successfully calculated and compared to the experiments.

Résumé :

This chapter discusses interconversion phenomena between spin and mechanical angular momtum. In moving objects, the spin gauge fields emerge from inertial effects and produce angular momentum transfer between mechanical motion and spin. Such spin-mechanial effects are predicted by quantum theory in non-inertial frames, and confirmed by recent experiments including the resonance frequency shift in NMR, the stray field measurement of rotating metals, and the inverse spin Hall voltage generation in liquied metals. These spin-mechanical effects that arise via the spin-gauge fields open a new field of spintornics, where spin and mechanical motion couple harmoniously.

Texte intégral

Résumé :

This chapter discusses the effects of a spin current injected into a uniformly magnetized ferromagnetic cell. The junction consists of two ferromagnetic layers separated by a nonmagnetic metal interlayer or insulating barrier layer. With a nonmagnetic metal interlayer, the junction is called a giant magnetoresistive nanopillar, and with an insulating barrier layer a magnetic-tunnel junction. When charge current is passed through this device, the electrons are first spin polarized by the fixed layer and spin-polarized current is then injected into the free layer through the nonmagnetic interlayer. This spin current interacts with the spins in the host material by an exchange interaction and exerts a torque. If the exerted torque is large enough, magnetization in the free layer is reversed or continuous precession is excited.

Texte intégral

Résumé :

This chapter begins with a definition of spin Hall effects, which are a group of phenomena that result from spin–orbit interaction. These phenomena link orbital motion to spin direction and act as a spin-dependent magnetic field. In its simplest form, an electrical current gives rise to a transverse spin current that induces spin accumulation at the boundaries of the sample, the direction of the spins being opposite at opposing boundaries. It can be intuitively understood by analogy with the Magnus effect, where a spinning ball in a fluid deviates from its straight path in a direction that depends on the sense of rotation. spin Hall effects can be associated with a variety of spin-orbit mechanisms, which can have intrinsic or extrinsic origin, and depend on the sample geometry, impurity band structure, and carrier density but do not require a magnetic field or any kind of magnetic order to occur.

Résumé :

This chapter presents an alternative method of injecting spin-polarized electrons into a nonmagnetic semiconductor through photoexcitation. This method uses circularly-polarized light, whose energy needs to be the same as, or slightly larger than, the semiconductor band-gap, to excite spin-polarized electrons. This process will introduce a spin-polarized electron-hole pair, which can be detected as electrical signals. Such an optically induced spin-polarized current can only be generated in a direct band-gap semiconductor due to the selection rule described in the following sections. This introduction of circularly polarized light can also be used for spin-polarized scanning tunnelling microscopy.

Résumé :

This article reviews recent advances towards the development of a truly atomistic time-dependent theory for spin-dynamics. The focus is on the s-d tight-binding model [where conduction electrons (s) are exchange-coupled to a number of classical spins (d)], including electrostatic corrections at the Hartree level, as the underlying electronic structure theory. In particular, the article considers one-dimensional (1D) magnetic atomic wires and their electronic structure, described by means of the s-d model. The discussion begins with an overview of the model spin Hamiltonian, followed by molecular-dynamics simulations of spin-wave dispersion in a s-d monoatomic chain and spin impurities in a non-magnetic chain. The current-induced motion in a magnetic domain wall (DW) is also explored, along with how an electric current can affect the magnetization landscape of a magnetic nano-object. The article concludes with an assessment of spin-motive force, and especially whether a driven magnetization dynamics can generate an electrical signal.

Résumé :

Chapter 18 This chapter discusses the spin Seebeck effect (SSE), which stands for the generation of a spin current, a flow of spinangular momentum, as a result of a temperature gradient in magnetic materials. In spintronics and spin caloritronics, the SSE is of crucial importance because it enables simple and versatile generation of a spin current from heat. Since the SSE is driven by thermally excited magnon dynaimcs, the thermal spin current can be generated not only from ferromagnetic conductors but also from insulators. Therefore, the SSE is applicable to “insulator-based thermoelectric conversion” which was impossible if only conventional thermoelectric technologies were used. In this chapter, after introducing basic characteristics and mechanisms of the SSE, important experimental progresses, such as the high-magnetic-field response of the SSE and the enhancement of the SSE in multilayer systems, are reviewed.
