Coherent dynamics of localized spins coupled with a two-dimensional hole gas in diluted-magnetic quantum wells
arXiv:cond-mat/9903280 · doi:10.1103/PhysRevB.59.9822
Abstract
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.
