摘要: We analyze the ultrafast demagnetization after ultrashort laser excitation by a kinetic model based on Elliott-Yafet scattering processes. By applying complete Boltzmann integrals we trace majority and minority electrons as well phonons in sample. Additionally, allow for dynamical changes exchange splitting between electrons. find that our has potential to describe magnetization dynamics provides insights relaxation of non-equilibrium electron system.
