Abstract

The voltage-gated spin-orbit torque (VGSOT) field-free switching mechanism provides the combined benefit of voltage-control of magnetic anisotropy (VCMA), spin-orbit torque (SOT), and the effect of exchange bias produced by the anti-ferromagnetic electrode simultaneously paving the way for the development of a realistic, ultra-low-power next-generation MRAM. This paper presents a detailed analysis of VCMA-assisted SOT writing properties on the free layer of the perpendicular magnetic tunnel junction (pMTJ) device. The magnetization reversal process caused by SOT is observed to be dependent on the pulse duration, and the voltage applied at the corresponding terminal. Further, the impact of terminal voltages and pulse width to induce SOT and VCMA effect on switching delay is analyzed. We also investigated the exchange bias effect on free layer thickness and switching delay along with the antiparallel (AP) and parallel (P) resistance of the model. Finally, the influence of gate voltage on SOT switching characteristics is investigated.
