The method of the preceding paper is used to derive approximate results for the spin-spin correlation functions of a ferromagnet with dipole-dipole coupling between spins. This formalism employs the drone-fermion representation for spin f and a high density l/z classification of terms. Results are obtained for the spin wave energy and damping as functions of momentum and temperature. As in the case of the Heisenberg model, it is found that the damping is small for any temperature below T, for sufficiently long wavelengths.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
