Description
Current-induced spin orbit torques are well established as a powerful method to manipulate magnetic thin films, with latest works demonstrating magnetization reversal down to the sub-ns scale. The reversal mechanism is a two-step process determined by domain wall nucleation and propagation. Recent work indicates that the domain nucleation process is a bottleneck for energy efficient switching. In this work we present a novel technique to fabricate coupled in-plane and out-of-plane magnetized lateral interfaces, where the Dzyaloshinskii–Moriya interaction lowers the energy barrier for domain wall nucleation and provides additional means of control over current-induced switching.
