Spin-orbit torque in a three-fold-symmetric bilayer and its effect on magnetization dynamics

Wuzhang Fang, Edward Schwartz, Alexey A. Kovalev +1

Field-free switching of perpendicular magnetization has been observed in an epitaxial L1${}_1$-ordered CoPt/CuPt bilayer and attributed to spin-orbit torque (SOT) arising from the cr…
