Spin orbit torque(SOT) driven magnetization switching has recently attracted attention towards next generation magnetic memory. Although SOT switching with perpendicular magnetization anisotropy (PMA) is attractive for high-speed and long-retention applications, bias field is necessary for a deterministic switching. In this study, we investigate bias field effect on the SOT switching with PMA by means of micromagnetic simulation, and newly propose a stable and fast magnetization switching assisted by canted magnetic fields.
