From: Spin-orbit torques and their associated effective fields from gigahertz to terahertz
Components of the spin-orbit torques \({{\boldsymbol{\tau }}}^{{\rm{SOT}}}\) that are in-phase with the oscillatory electric field for the magnetic moment along the directions indicated in a: \(z\to x\) (green), \(z\to y\) (red) and \(x\to y\) (blue). The torques are decomposed in b field-like, c damping-like and d longitudinal components for two distinct frequencies: static limit \(\omega =0\) (solid lines) and \({\omega }_{{\rm{res}}}^{z}\) = 1.5 THz (dashed lines). The torques are given in units of \(e{a}_{0}=8.48\times 1{0}^{-30}\) Cm, where \(e\) is the electronic charge and \({a}_{0}\) is the Bohr radius.
