Fig. 4: Polarization dependence of ISHE in thin-film α-Fe2O3/Pt.
From: Probing polarization-tunable sub-terahertz spin pumping in bimodal α-Fe2O3/Pt
a, b Polarization contour map of VISHE at 130 GHz in the Voigt (a) and Faraday (b) geometries. Traces are averaged over 4 (8) field sweeps for the Voigt (Faraday). c, d Polar plot of the signal maximum with respect to the MPI phase delay for Voigt (c) and Faraday (d) contours. Solid blue and orange lines are fits to a two-term tilted sine function. Dashed lines indicate \({\boldsymbol{\phi }}\) at the maximum amplitude of \({{\boldsymbol{V}}}_{{\boldsymbol{ISHE}}}\).
