Enhanced spin-orbit torques and perpendicular magnetic anisotropy in CoFeB/MgO structures with Ta/W bilayer
Spin-orbit torques (SOTs) and the perpendicular magnetic anisotropy (PMA) in Ta/W/CoFeB/MgO structures have been investigated by varying the thickness of the W layer. Addition of the W layer gives rise to enhancement of the annealing stability and perpendicular anisotropy field. After annealing at h...
