Abstract
Recent theoretical work on the response functions observed in magnetic neutron scattering and muon spin relaxation experiments is briefly surveyed. Coupled-mode theory is found to provide a tolerable account of experiments performed on the paramagnetic and critical regions over a wide range of frequencies and wave vectors.
