Abstract
Spin-orbit coupling (SOC) can convert a charge current into a spin current, enabling electrical control of magnetization, the foundation of spintronic devices. A quintessential example of SOC-induced transport in a ferromagnetic conductor (FM) is the anomalous Hall effect (AHE), in which an electric current perpendicular to the magnetization generates a transverse spin current and charge accumulations on the surface. Applying similar considerations to the configuration of a current parallel to the magnetization, SOC should also give rise to a transverse spin current with spins orthogonal to both the magnetization and spin current. The transverse spins precess rapidly about the magnetization direction and exert torque on the magnetization as they dephase, in analogy with spin transfer torque. In this talk, we will discuss this transverse spin Hall effect (TSHE) leads to anomalous spin-orbit torque (ASOT) on the top and bottom surfaces of a FM. In addition, we will also discuss the
