AC measurement current transformer

The ability to switch magnetic elements via spin-orbit-induced torque has attracted much attention recently, contributing to the realization of high-performance nonvolatile memories with low power consumption. To achieve efficient spin-orbit-based switching, new materials and novel physics are needed to obtain high charge-spin conversion efficiency, so the choice of spin source is crucial. In view of this, Professor Hyunsoo Yang of the National University of Singapore and others recently reported the observation of spin-orbit torque (SOT) switching in a bilayer consisting of 1T'-MoTe2 semi-metallic films adjacent to permalloy. Deterministic switching can be achieved at room temperature without external magnetic fields, and the current during switching is an order of magnitude smaller than the typical current in the best-performing heavy metal devices. If the contribution of the interface spin orbit is considered in addition to the overall spin Hall effect, the reason for its thickness dependence can be understood. With the help of dumbbell-shaped magnetic elements, the switching current is further reduced by a factor of three. The findings of this article show that MoTe2 has important application prospects in the field of low-power semi-metallic spin devices.
