Description
Femtosecond laser pulse induced magnetization reversal of α-Gd23.1Fe71.9Co5.0 was investigated by time-resolved measurements of the polar Kerr-rotation. The dynamics is found to follow the Bloch-equation via a relaxation time that does not depend on temperature but strongly decreases with increasing excitation density. A minimum value of (190±40)ps was obtained for the highest applicable pump-fluence. Comparing the reversal dynamics to temperature induced variations of magnetization within a single domain state and to the magnetization dynamics measured in remanence, the different contributions of transient temperature and domain formation to the magnetic response are separated.
