THE INTERACTION OF S-ELECTRONS WITH SPIN WAVES IN A FERROMAGNETIC,
Abstract
In this paper, the emission and absorption of spin waves by s-electrons and the attenuation of spin waves caused by the interaction of s-electron and spin-wave scattering are computed using the double-time Green function. The results show that at low temperatures, only those waves with wave vectors at 10 to the 6th < k < 10 to the 8th are emitted or absorbed by s-electrons. The attenuation of waves thus produced is much greater than that caused by spin-wave interaction. The attenuation due to scattering of spin waves by s-electrons is less than that due to the scattering of spin waves among themselves. It is therefore possible that there is an absorption band at 10 to the 6th < k < 10 to the 8th. (Author)
