Fig. 4: Ratios between damping-like and field-like components of the spin-orbit torques.
From: Spin-orbit torques and their associated effective fields from gigahertz to terahertz
Frequency and angular dependencies of the ratios between the damping-like, \({\tau }_{{\rm{DL}}}(\omega )\), and field-like, \({\tau }_{{\rm{FL}}}(\omega )\), components of the spin-orbit torques: a in-phase and b out-of-phase contributions, and c amplitudes. The magnetic moment is rotated in the \(zx\) plane, \(z\) is the normal to the film surface and the electric field is applied along \(x\).
