Abstract
Precession of magnetization induced by laser pulses in (Ga,Mn)As was studied by the pump-and-probe technique. We concentrated on various experimental aspects that can be used to identify a part of the measured magneto-optical signals that provides information about the dynamics of magnetization.
We also revealed that the fact that it takes about 80 ps before the quasi-equilibrium precession of magnetization is initiated by the impact of laser pulse.
