【 摘 要 】

Spin dynamics in a quantum well made of diluted-magnetic semiconductor is studied theoretically. The exchange interaction of the ensemble of localized spins with two-dimensional heavy-hole gas is shown to affect time evolution of the spin system in an in-plane magnetic field. The Larmor frequency of localized spins is reduced under influence of an oscillating effective field of holes. [S0163-1829(99)07615-8].
