Abstract

Demagnetization of ferromagnets initiated by pulsed laser has attracted attention due to ultrafast magnetism quenching within less than a picosecond timescale. The mechanisms for demagnetization have been discussed for a long time and most discussions have focused on secondary processes with angular momentum dissipation [1] and thermal processes [2].
