This paper presents the boundary conditions needed for drift-diffusion models to treat interfaces with spin-orbit coupling. Using these boundary conditions for heavy metal/ferromagnet bilayers, solutions of the drift-diffusion equations agree with solutions of the spin-dependent Boltzmann equation and allow for a much…

This article performs computer simulations of the change in magnetization in the ferromagnetic film when polarized electric current passes through it. The model examines multilayer structures from ferromagnetic and nonmagnetic films. A sandwich system comprises two ferromagnetic layers separated by a nonmagnetic…

In this review article, an insight of the physics that explains the phenomenon of torques induced by currents in systems comprising ferromagnetic (FM)-non-magnetic (NM) materials has been provided with particular emphasis on experiments that concern the observation of such torques. An important requirement of systems…

We consider theoretically the impact of Rashba spin-orbit coupling on spin torque oscillators (STOs) in synthetic ferromagnets and antiferromagnets that have either a bulk multilayer or a thin film structure. The synthetic magnets consist of a fixed polarizing layer and two free magnetic layers that interact through…

'Dong-Ok Kim' 'Kyung Mee Song' 'Dongseuk Kim' 'Byong Sun Chun' 'Chanyong Hwang'] Current-induced magnetic domain wall (DW) motion is an important operating principle of spintronic devices. Injected current generates spin torques (STs) on the DWs in two ways. One is the spin transfer from magnetic domains to the walls…

The spin-transfer torque is a fundamental physical quantity to operate the spintronics devices such as racetrack memory. We theoretically study the spin-transfer torque and analyze the dynamics of the magnetic domain walls in magnetic Weyl semimetals. Owing to the strong spin-orbit coupling in Weyl semimetals, the…

'Vincent Cros' 'F. Nguyen Van Dau' 'A. Fert'] The discovery that a spin polarized current can exert a large torque on a ferromagnet through a transfusion of spin angular momentum, offers a new way to control a magnetization by simple current injection, without the help of an applied external field. Spin transfer can be…

An emerging field of spintronics, spin-orbitronics, aims to discover novel phenomena and functionalities originating from spin-orbit coupling in solid-state devices. The development of spin-orbitronics promises a fundamental understanding of spin physics in condensed matter, as well as smaller, faster, and far-more…

A three-dimensional description of spin-dependent current transport across nonmagnetic/ferromagnetic interfaces with strong interfacial spin-orbit coupling is presented. The resulting current-induced torques acting on the magnetization of the ferromagnetic layer are addressed. By considering both magnetic exchange and…

'Jairo Sinova' 'Jakub Železný'] Electrical spin-current generation is among the core phenomena driving the field of spintronics. Using ab initio calculations we show that a room-temperature metallic collinear antiferromagnet RuO2 allows for highly efficient spin-current generation, arising from anisotropically-split…

Spins transverse to the magnetization of a ferromagnet only survives over a short distance. We develop a drift-diffusion approach that captures the main features of transverse spin effects in systems with arbitrary spin textures (vortices, domain walls) and generalizes the Valet-Fert theory. In addition to the standard…

We provide a general formulation of the spin-orbit coupling on a 2D curved surface. Considering the wide applicability of spin-orbit effect in spinor-based condensed matter physics, a general spin-orbit formulation could aid the study of spintronics, Dirac graphene, topological systems, and quantum information on…

Electroactive bacteria export metabolic electrons through cytochrome-based extracellular electron-transfer (EET) conduits. Although purified S. oneidensis EET cytochromes are chiral and spin-selective, the functional impact of chirality-induced spin selectivity in live cultures remains unknown. Here, we show that a…

The search for hybrid materials with outstanding electronic performance is highly demanding Since copper corroles have emerged as versatile building blocks providing outstanding electronic, and reactivity properties, a new series of non-covalent hybrid materials were computationally investigated based on pristine…

We introduce a class of pulsed third-spin-assisted recoupling (P-TSAR) magic-angle-spinning (MAS) solid-state NMR techniques that achieve efficient polarization transfer over long distances to provide important restraints for structure determination. These experiments operate with the same principle as continuous-wave…

Biological energy conversion relies on highly efficient electron transfer. The chirality induced spin selectivity (CISS) effect, which couples electron spin to momentum in chiral molecules, is hypothesized to promote this efficiency. While observed in isolated biomolecules, the physiological relevance of CISS during…

Living systems rely on molecular building blocks of low symmetry such as amino-acids and nucleotides, which generally yield short-lived magnetic transitions in response to electromagnetic radiation. This is the first demonstration that in proteins of relatively large size local magnetic symmetry can be induced to…

Cross-polarization (CP) is an indispensable part of solid-state nuclear magnetic resonance (NMR) spectroscopy to enhance sensitivity and extract quantitative structural information. However, the most common versions of the CP experiments are susceptible to the presence of anisotropic interactions, including chemical…

In this study, we report a two-dimensional NMR technique that correlates the chemical shifts of homonuclear spin systems in solids under MAS. The pulse sequence employs double spin-lock RF pulses to facilitate magnetization exchange among low-γ nuclei (such as ^13^C or ^15^N) through cross-relaxation driven by a…

We derive a systematic and general method for parametrizing coarse-grained molecular models consisting of anisotropic particles from fine-grained (e.g. all-atom) models for condensed-phase molecular dynamics simulations. The method, which we call anisotropic force-matching coarsegraining (AFM-CG), is based on rigorous…

Zig-zag graphene nanoribbons (ZGNRs) are known to possess spin moments at the hydrogenterminated edge carbon atoms, thus the spin-polarized electron transmission is expected while the current is longitudinally passed through the ZGNRs. However, in pristine ZGNRs, the spin polarized transmission is not observed due to…

This article is the second in a two-part tutorial review on electronic spin-dependent dynamics. In Part I, we presented the fundamental theory within the adiabatic Born– Huang framework that describes the interaction between nuclear motion and the elec- tronic (spin and spatial) degrees of freedom. In particular, we…
