Conversion of spin current into charge current at room temperature: Inverse spin-Hall effect
The inverse process of the spin-Hall effect (ISHE), conversion of a spin current into an electric current, was observed at room temperature. A pure spin current was injected into a Pt thin film using
Theory of current-driven domain wall motion: spin transfer versus momentum transfer.
A self-contained theory of the domain wall dynamics in ferromagnets under finite electric current is presented and the momentum-transfer effect dominates, and the threshold current for wall motion is proportional to V(0)/rho(w), V0 being the pinning potential.
Resistivity due to a Domain Wall in Ferromagnetic Metal
The resistivity due to a domain wall in ferromagnetic metallic wire is calculated based on the linear response theory. The interaction between conduction electrons and the wall is expressed in terms

A brief review of field- and current-driven domain-wall motion
A brief review of field- and recently developed current-driven domain-wall motion in a ferromagnetic nanowire is presented from a theoretical point of view. In the first part, the wall motion driven
Chirality-Driven Anomalous Hall Effect in Weak Coupling Regime
Anomalous Hall effect arising from non-trivial spin configuration (chirality) is studied treating perturbatively the exchange coupling to localized spins. Scattering by normal impurities is included.
Current-induced magnetic vortex motion by spin-transfer torque
We investigate the dynamics of a magnetic vortex driven by spin-transfer torque due to spin current in the adiabatic case. The vortex core represented by collective coordinate experiences a
Emergent Spin-Orbit Torques in Two-Dimensional Material/Ferromagnet Interfaces
Heterostructures of two-dimensional (2D) materials provide a testbed for interface-induced magnetic phenomena owing to their hybridized electronic structure with a strong interplay between spin and

A microscopic formalism to calculate thermal transport coefficients is presented based on a thermal vector potential, whose time derivative is related to a thermal force, which indicates that the thermalvector potential couples to the energy current via the minimal coupling.
