| 中文摘要 | time-resolved kerr rotation measurement in the (ga,mn)as diluted magnetic semiconductor allows direct observation of the dynamical properties of the spin system of the magnetic ions and the spin-polarized holes. experimental results show that the magnetic ions can be aligned by the polarized holes, and the time scales of spin alignment and relaxation take place in tens and hundreds of picoseconds, respectively. the larmor frequency and effective g factor obtained in the voigt geometry show an unusual temperature dependence in the vicinity of the curie temperature due to the exchange coupling between the photoexcited holes and magnetic ions. such a spin coherent precession can be amplified or destructed by two sequential excitation pulses with circularly copolarized or oppositely polarized helicity, respectively.
