Generating Unconventional Spin‐Orbit Torques With Patterned Phase Gradients in Tungsten Thin Films
Advanced Materials, EarlyView.ABSTRACT A key aim in spintronics is to achieve current‐induced magnetization switching via spin‐orbit torques without external magnetic fields. For this, the focus of recent work has been on introducing controlled lateral gradients across ferromagnet/heavy‐metal devices, giving variations in thickness, composition, or interface quality.
