LIT images. (a,b) Raw amplitude A (a) and phase ϕ (b) images for the Pt-W/YIG sample at Jc = 2.7 mA and f = 25.0 Hz, measured in the SPE condition (see Fig. 1(b)). The left and right images were measured at the magnetic fields of H = +500 Oe and −500 Oe, respectively. (c) Schematic illustration of the Pt-W/YIG sample from a top view. (d,e) Aodd (d) and ϕodd (e) images for the Pt-W/YIG sample. The Aodd and ϕodd images are obtained by subtracting the raw LIT images at H = −500 Oe from those at H = +500 Oe and dividing the subtracted images by 2 (see the definition in the main text). (f,g) A (f) and ϕ (g) images for the Pt-W/YIG sample at Jc = 2.7 mA, f = 25.0 Hz, and H = 0 Oe, measured in the Joule-heating condition (see Fig. 1(c)).
