Résumé

The electronic and magnetic properties of Gd have been studied using time-and angle-resolved photoelectron spectroscopy employing laser pump and synchrotron radiation probe pulses. The static temperature evolution of the valence band and more precisely, the 5d6s exchange splitting is reported. Ultrafast demagnetization is measured using dichroic resonant Auger spectroscopy. Remarkably, a complete demagnetization is observed followed up by a non-monotonic recovery that could be associated to magnetization oscillations.
