Magnetic oscillation of the transverse domain wall in a penta-layer MgO-MTJ

The switching probability of In-Plane penta-layer MTJs for different switching current densities and pulse durations is investigated by means of extensive micromagnetic simulations. We reveal a non-negligible probability of the formation of a vortex state/transverse domain wall during switching. Based on the current-induced transverse domain wall periodic motion a new type of magnetic nano-oscillator is proposed.
