Abstract

Magnetic switching devices, including magnetic memory devices, are provided. The devices use high-quality crystalline films of 4d or 5d transition metal perovskite having a strong spin-orbit coupling (SOC) to produce spin-orbit torque in adjacent ferromagnetic materials via a strong spin-Hall effect. Spin-orbit torque can be generated by the devices with a high efficiency, even at or near room temperature.
