Fig. 3: Faraday polarization dependence of ISHE for the acoustic branch.
From: Probing polarization-tunable sub-terahertz spin pumping in bimodal α-Fe2O3/Pt
a Contour map of the polarization dependence of VISHE at 120 GHz in the Faraday geometry. Traces are averaged over 16 field sweeps taken in 3.75° steps. b Theoretical planar projection of the magnetization dynamics of \(\omega 0\) from the perspective of the microwave beam. Dashed lines indicate the motion of \(m0\) within the \({zy}\) plane. The canting angle of the magnetization is exaggerated for visual clarity. c Polar plot of the signal maximum with respect to the MPI phase delay. Solid lines are fits to a two-term tilted sine function.
