Multi-Faceted Spin Orbit Torque Phenomena in GdCo (Berkeley)


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 g... » read more

Field-free spin-orbit torque-induced switching of perpendicular magnetization in a ferrimagnetic layer with a vertical composition gradient


Abstract "Current-induced spin-orbit torques (SOTs) are of interest for fast and energy-efficient manipulation of magnetic order in spintronic devices. To be deterministic, however, switching of perpendicularly magnetized materials by SOT requires a mechanism for in-plane symmetry breaking. Existing methods to do so involve the application of an in-plane bias magnetic field, or incorporation o... » read more
