Electronic mechanism of sub-100-fs demagnetization induced by a femtosecond light pulse
Theoretical prediction that light pulses from optical to X-ray regimes cause sub-100 fs demagnetization via electronic excitation and electron redistribution in the magneto-sensitive band, without significant phonon or Heisenberg exchange contributions.
