Fig. 4: Spin-to-charge conversion and SOT-switching measurements of PMA-YIG/Pt bilayer.

a Measured thermoelectric signal in Pt layer with the magnetic field swept along the y-direction. b Measured thermoelectric signal in Pt layer as a function of the magnetic field when it sweeps along the z-direction with a constant 6-mT magnetic field applied along the +x (blue) and −x (red) direction. c Measured thermoelectric signal in Pt layer as a function of the magnetic field when it sweeps along the x-direction with a constant 20-mT magnetic field applied along the +z (green) and −z (pink) direction. d Out-of-plane hysteresis loop of PMA-YIG/Pt measured by P-MOKE. e The current-driven SOT-switching of PMA-YIG/Pt at different μ0Hx. f SOT-switching loop amplitude (Ampl.) of PMA-YIG/Pt as a function of μ0Hx.
