Spin-orbit torques and their associated effective fields from

Index

Abstract

This paper investigates the dynamical transverse components of spin-orbit torques (SOTs) and uncovers longitudinal contributions to the magnetic moment capable of changing its magnitude. The study reveals that while SOTs are drastically altered in the dynamical regime, the associated effective magnetic fields exhibit frequency-independent behavior from the static limit up to the terahertz domain, including the ferromagnetic resonance of the system. These findings suggest new ways to control magnetic units in next-generation spintronic devices.
