Spin-orbit Torques in CoPt Multilayers

October 30, 2018 | PAPERS · NONEQUILIBRIUM GREEN'S FUNCTIONS

Spin-orbit Torques in CoPt Multilayers We have demonstrated the feasibility of calculating the spin-orbit torques in layered systems within density-functional theory, augmented by an Anderson model to treat disorder. Terms beyond the usual damping-like and field-like torques were found. While the torques that contribute to damping are almost entirely due to spin-orbit coupling on the Pt atoms, the field-like torque does not require it.
