| Popis: | We investigate ultrafast magnetization dynamics due to electron-phonon interaction in a ferromagnetic model sys- tem including spin-orbit coupling. By computing the reduced spin-density matrix and Boltzmann-type scattering integrals, we identify the microscopic mechanism with which the electronic spin is dissipated by electron-phonon scattering processes in ferromagnets. We present in some detail the numerical approach used to compute the scattering dynamics and discuss problems that arise in treating these dynamics. |
