Abstract:
In recent years it has been demonstrated that magnetization can be changed without applying an external magnetic field in extremely short timescales of the order of hundreds of femtoseconds [1]. We have studied the effect by means of ab initio calculations for three ferromagnetic metals Fe, Co and Ni [2] considering the Elliott-Yafet electron-phonon spin-flip (SF) scattering [3] which has been suggested to be the dominant microscopic mechanism.
