Spin-transfer torque generated by a topological insulator
TLDR
It is found that the strength of the torque per unit charge current density in Bi2Se3 is greater than for any source of spin-transfer torque measured so far, even for non-ideal topological insulator films in which the surface states coexist with bulk conduction.
Current-induced spin-orbit torques in ferromagnetic and antiferromagnetic systems
Spin-orbit coupling in inversion-asymmetric magnetic crystals and structures has emerged as a powerful tool to generate complex magnetic textures, interconvert charge and spin under applied current,
Nonequilibrium intrinsic spin torque in a single nanomagnet
In a single nanomagnet with spin-orbit interactions, the electrical current can generate a nonequilibrium spin density that gives rise to a spin torque on the magnetization. This spin torque does not
First-principles investigation of the very large perpendicular magnetic anisotropy at Fe|MgO and Co|MgO interfaces
The perpendicular magnetic anisotropy (PMA) arising at the interface between ferromagnetic transition metals and metallic oxides are investigated via first-principles calculations. In this work very
Current induced torques and interfacial spin-orbit coupling: Semiclassical modeling
In bilayer nanowires consisting of a ferromagnetic layer and a nonmagnetic layer with strong spin-orbit coupling, currents create torques on the magnetization beyond those found in simple
New perspectives for Rashba spin-orbit coupling.
TLDR
This Review discusses relevant recent and ongoing realizations of Rashba physics in condensed matter, ranging from layered graphene-like materials to cold atoms.
Theory of spin torque due to spin-orbit coupling
The combined effect of spin-orbit coupling and exchange interaction in a single ferromagnetic layer is investigated. It is shown that, in nonequilibrium regime, the spin-orbit interaction (SOI) gives
Bias-voltage dependence of perpendicular spin-transfer torque in asymmetric MgO-based magnetic tunnel junctions
Spin-transfer torque allows the magnetization of nanopillar devices to be switched electrically. Incorporating asymmetries into the design of such a device generates a linear out-of-plane torque
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
Antiferromagnetic spintronics
Antiferromagnetic materials could represent the future of spintronic applications thanks to the numerous interesting features they combine: they are robust against perturbation due to magnetic
