a Schematic showing ST-FMR measurement technique and detection principle for Pt(P)/NiFe, along with an optical image of the micro-device. b ST-FMR voltage \({V}_{{\rm{mix}}}\) obtained at f = 5 GHz with the de-convoluted symmetric and antisymmetric component fitted using Eq. (1) for Pt/NiFe and Pt(P)/NiFe. c \({\theta }_{{\rm{SH}}}^{{\rm{LS}}}\) plotted as a function of \(f\) for Pt/NiFe and Pt(P)/NiFe.
