We demonstrate magnetization switching in out-of-plane magnetized Ta\CoFeB\MgO nanowires by current pulse injection along the nanowires, both with and without a constant and uniform magnetic field collinear to the current direction. We deduce that an effective torque arising from spin-orbit effects in the multilayer drives the switching mechanism. While the generation of a component of the magnetization along the current direction is crucial for the switching to occur, we observe that even…

Temperature dependence of the spin torque effect in current-induced domain wall motion.
It is observed that, in contrast with field-induced domain wall motion, which is a thermally activated process, the critical current density for current-induceddomain wall motion increases with increasing temperature, which implies a reduction of the spin torque efficiency.
