Non-local field-like spin-orbit torques in Rashba systems: an ab-initio study of Ag${}_2$Bi/Ag/Fe film

Guillaume Géranton, Bernd Zimmermann, Nguyen H. Long +4

We investigate from first principles the field-like spin-orbit torques (SOTs) in a Ag${}_2$Bi-terminated Ag(111) film grown on ferromagnetic Fe(110). We find that a large part of t…
