摘要：

We study the effects of the reaction field on the spin relaxation. We find that they are not only responsible for a nonlinear frction process, as recently pointed out by several authors, but, in the case of sufficiently strong coupling, they also result in a bistable precession process. This implies that at weak temperatures the rate of the spin relaxation is expected to exhibit an Arrhenius-like dependence on temperature.
