Ultrafast demagnetization of ferromagnetic transition metals: The role of the Coulomb interaction

Ultrafast demagnetization of ferromagnetic transition metals: The role of the Coulomb interaction

The Elliott-Yafet (EY) mechanism is arguably the most promising candidate to explain the light-induced ultrafast demagnetization dynamics in ferromagnetic transition metals on time scales on the order of 100 fs. So far, only electron-phonon (or impurity) scattering has been analyzed as the scattering process needed to account for the demagnetization. …
