摘要：

The relaxation towards thermal equilibrium of a magnetic polaron bound at an impurity located near the interface of a quantum well structure is calculated. The relaxation is induced by the exchange interaction between the localized spins in the polaron and the randomly aligned localized spins in the barrier. Relaxation of the polaron occurs at two different rates. Fast relaxation is associated with an intravalley relaxation while slow relaxation describes the flip-flop motion of the whole polaron.
