a Schematic of experimental setup for ISHE voltage measurements. b VSP vs. Hext spectra of VO2(68 nm)/YIG (3 μm) bilayer at θH = 90° (blue) and 270° (red) at T = 20 °C. c VSP spectra of VO2 (68 nm)/YIG(3 μm) across the transition; the plots for different temperatures are shifted upwards by 30 μV for clarity. Temperature dependence of d VSP (stars) and resistivity (line) of theVO2(68 nm)/YIG(3 μm) sample (e) Resonant field from experiment (red) and calculated from Kittel’s formula (blue) at 8 GHz. (f) VSP vs. Hext for Pt(6 nm)/YIG bilayers sample at different temperatures; plots for different temperatures are shifted by 10 μV for clarity.
