Photo-induced demagnetization and recovering dynamics in CoPt
by Lee Yeon (

1. less than few tens of femtoseconds, the photon field interacts with the electronic charges and spins. 2. few tens to hundreds of femtoseconds, the relaxation of the electrons and spins to thermalized populations 3. longer than few hundreds of femtoseconds, the heat exchange between the charges and the spins with the lattice
