A new technical paper titled “Tunable multistate field-free switching and ratchet effect by spin-orbit torque in canted ferrimagnetic alloy” was published by researchers at UC Berkeley and Lawrence Berkeley National Laboratory.
The paper states:
“Spin-orbit torque is not only a useful probe to study manipulation of magnetic textures and magnetic states at the nanoscale but also it carries great potential for next-generation computing applications. Here we report the observation of rich spin-orbit torque switching phenomena such as field-free switching, multistate switching, memristor behavior and ratchet effect in a single shot, co-sputtered, rare earth-transition metal GdxCo100−x.”
