摘要：

A magnon-photon interaction is constructed for the magnetic vector of the radiation field parallel to the direction of magnetization in a ferromagnet. The ellipticity problem is solved by introducing several transformations. The dominant contributions to the self-energy are written down using the second-order perturbation theory and from that the radiative relaxation times are calculated. Besides some other interesting dependences, the relaxation times of magnons arising from the new processes are found to depend on temperature and the microwave power. © 1979.
