An analog of a photoelectromagnetic effect has been discovered in optical transitions between Landau levels in rc-type InSb. The effect is of odd parity in the magnetic field. The primary reason for the onset of a photo-emf is a spatial separation of nonuniformly excited carriers due to a difference between the diffusion for hot and cold electrons at the Landau ground level. The electron thermalization time has been determined.
