(a) Schematic diagram of the ITO(100 nm)/YIG sample and electrical measurement geometry. The stripe and the Hall bar were used for spin pumping and LSSE measurements, respectively. (b) ISHE voltage as a function of H along y axis for the as-prepared ITO/YIG, annealed ITO/YIG, and Pt/YIG. (c) FMR linewidths of YIG, Pt/YIG, as-prepared ITO/YIG, and annealed ITO/YIG structure as a function of the microwave frequency.
