Spin–orbit torque magnetization switching is an efficient method to control magnetization. In perpendicularly magnetized films, two types of spin–orbit torque are induced by driving a current: a damping-like torque and a field-like torque. The da

Spin-orbit torque (SOT) magnetization switching is an efficient method to control magnetization. In SOT switching, controlling a field-like torque strength is indispensable to reduce the critical current density; however, this is difficult because th
To achieve a desirable magnitude of spin-orbit torque (SOT) switching and realise multifunctional spin logic and memory devices utilising SOT, controlling the SOT manipulation is vitally important. In conventional SOT bilayer systems, researchers hav

We fabricate a vertical spin metal-oxide-semiconductor field-effect transistor (spin-MOSFET) structure, which is composed of an epitaxial single-crystal heterostructure with a ferromagnetic-semiconductor GaMnAs source/drain, and investigate its spin-
