Enhanced spin–orbit torques by oxygen incorporation in tungsten films

When interfaced with a current-carrying heavy metal, spin orbit effects can generate a torque on the magnetization of a ferromagnet, understood as a bulk effect. Here, the authors show evidence of an interfacial contribution to such spin orbit torque in O-doped W/CoFeB thin film systems.
