(color online) Angular dependence of Vy upon illumination of 360 nm laser with a power of (a) 0 mW, (b) 3.5 mW, (c) 7.2 mW, and (d) 12 mW. (e), (f), (g) and (h) show the polar graphs transferred from (a), (b), (c), and (d), respectively. The rotating magnetic field H is 500 Oe. Symbols represent the experimental data and solid lines are the results of curve fitting based on Eq. (2). The current with a magnitude of 50 μA is applied in the x direction, and α is the angle between the applied magnetic field and the current direction, as defined in (i). (j) The laser power dependence of the fitting results of VISHE and VSMR from Eq. (2).
