Thermally activated switching of perpendicular magnet by spin-orbit spin torque
Thermally activated switching of perpendicular magnet by spin-orbit spin torque
We theoretically investigate the threshold current for thermally activated switching of a perpendicular magnet by spin-orbit spin torque. Based on the Fokker-Planck equation, we obtain an analytic expression of the switching current, in agreement with numerical result. We find that thermal energy barrier exhibits a quasi-linear dependence on the current, …
