From: Spin-orbit torques and their associated effective fields from gigahertz to terahertz
a Field-like, b Damping-like and c Longitudinal components of the effective field \({{\bf{B}}}_{i}^{{\rm{eff}}}(\omega )\), given by Eq. (6), in the local frame of reference that are in phase with the oscillatory electric field, when the magnetic moment of the ferromagnetic layer in the Fe/W(110) bilayer is rotated within the \(zx\) plane by an external magnetic field.
