VISHE measured via a red laser with a wavelength of 808 nm. The temporal evolution of VISHE signals for different directions of magnetic fields in response to a laser turned on at 60 s and off at 90 s with (a) top-light and (b) bottom-light configurations, respectively. c Sketch of the physical mechanism on SPVE in W/YIG system.
