Spin-orbit torque in a magnetic domain wall was investigated by solving the Pauli-Schr\"{o}dinger equation for the itinerant electrons. The Rashba interaction considered is derived from the violation of inversion symmetry at interfaces between ferromagnets and heavy metals. In equilibrium, the Rashba spin-orbit interaction gives rise to a torque corresponding to the Dzyaloshinskii-Moriya interaction. When there is a current flowing, the spin-orbit torque experienced by the itinerant electrons…

An antidamping spin-orbit torque originating from the Berry curvature.
TLDR
The observation of an antidamping spin-orbit torque that stems from the Berry curvature, in analogy to the origin of the intrinsic spin Hall effect is reported, which is expected to be of comparable strength to the spin-Hall-effect-driven antidamping torque in ferromagnets interfaced with paramagnets with strong intrinsicspin Hall effect.

TLDR
The theory provides an explanation for the mechanism driving the magnetization switching in a single ferromagnet as observed in the recent experiments.
Angular dependence and symmetry of Rashba spin torque in ferromagnetic heterostructures
In a ferromagnetic heterostructure, the interplay between Rashba spin-orbit coupling and exchange splitting gives rise to a current-driven spin torque. In a realistic device setup, we investigate the
Current-induced torques in textured Rashba ferromagnets
In systems with small spin-orbit coupling, current-induced torques on the magnetization require inhomogeneous magnetization textures. For large spin-orbit coupling, such torques exist even without
Current-driven spin torque induced by the Rashba effect in a ferromagnetic metal layer.
TLDR
It is demonstrated that strong magnetic fields can be induced in ferromagnetic metal films lacking structure inversion symmetry through the Rashba effect and this process makes it a realistic candidate for room-temperature spintronic applications.
Current-induced torques and interfacial spin-orbit coupling
In bilayer systems consisting of an ultrathin ferromagnetic layer adjacent to a metal with strong spin-orbit coupling, an applied in-plane current induces torques on the magnetization. The torques

Fast current-induced domain-wall motion controlled by the Rashba effect.
TLDR
In an ultrathin Co nanowire, integrated in a trilayer with structural inversion asymmetry (SIA), the high spin-torque efficiency facilitates the depinning and leads to high mobility, while the SIA-mediated Rashba field controlling the domain-wall chirality stabilizes the Bloch domain- wall structure.
