a The magnetic field dependence of VISHE. b The voltage VTotal as a function of time were measured at different magnetic fields directions along the y axis, in response to light that was turned on at 60 s and then turned off at 90 s. c The time dependence of VISHE were extracted in Fig. 3b by subtracting the thermoelectric signal.
