Spin dynamics in (Ga,Mn)As films grown on GaAs(001) was investigated by Time-resolved magneto-optical Kerr effect. The Kerr signal decay time of (Ga,Mn)As without external magnetic field applied was found to be several hundreds picoseconds, which suggested that photogenerated polarized holes and magnetic ions are coupled as a ferromagnetic system. Nonmonotonic temperature dependence of relaxation and dephasing (R&D) time and Larmor frequency manifests that Bir–Aronov–Pikus mechanism dominates the spin R&D time at low temperature, while D’yakonov–Perel mechanism dominates the spin R&D time at high temperature, and the crossover between the two regimes is Curie temperature.
