摘要：
A Green function technique is used to study the effects of spin-phonon interactions in ferromagnetic semiconductors. The spin wave energy and the transverse damping for two different spin-phonon interaction mechanisms are evaluated for the first time beyond the RPA. The results are valid below and above T(c). The temperature dependence of these quantities is discussed, and is found to be in agreement with the experimental data.
