Thickness Dependence of Spin-Orbit Torques in Ferrimagnetic GdFeCo Alloys

Niklas Roschewsky, Charles-Henri Lambert, Sayeef Salahuddin

So far, studies of spin-orbit torques (SOT) in ferromagnets with perpendicular magnetic anisotropy (PMA) have been restricted to ultra thin samples, while a systematic study of its…
