Abstract
According to the fundamental equations of the relativistic quantum electrodynamics (QED) describing the light matter interaction, a femtosecond laser pulse can instantaneously modify the spin dynamics in a ferromagnetic material. It is this physical phenomenon that precedes the laser induced demagnetization occurring at the femtosecond time scale, that we have investigated using femtosecond optical pulses.
