Abstract :
We present a micromagnetic modeling study of spin transfer (ST) switching in magnetic tunneling junctions (MTJs) and its dependence on thermal effects due to a finite temperature of the MTJ. It is shown that the major effect of temperature is the introduction of nonzero distribution of local magnetization deviation from the easy axis of the free layer. The study of asymmetry between antiparallel (AP) to parallel (P) and P to AP switching is presented
