Spin-orbit torque (SOT) magnetoresistance (MR) devices have attracted attention for use in next-generation MR devices. The SOT devices are known to exhibit different write properties based on the relative angle between the magnetization direction of the free layer and the write-current direction. However, few studies that compare the write properties of each type have been reported. In this study, we measured the external perpendicular-magnetic field dependence of the threshold write current density and the write current switching probability using two types of in-plane magnetization SOT-MR devices.
