We theoretically study the mechanism of the all-optical VOLUME DRY TEXTURE SPRAY magnetic switching by combining the Rashba effect and stimulated Raman scattering.In hydrogenlike systems, we show that the Rashba effect splits the energy band and stimulated Raman scattering transits the electrons between the lambda three-level system and controls the spin states to reverse the orientation of magnetization.The dynamics of electrons are described with the Lindblad equation in a few hundreds Hammock of femtoseconds.

We further investigate the influence of laser intensity and wavelength on the probability of spin-flip in a ferromagnetic material, CoPt.
