Brillouin Scattering in Paramagnetic Crystals
The importance of Brillouin scattering in paramagnetic systems lies in the fact that it is relatively easy to generate microwave phonons of different frequencies, to detect these optically and to study their interaction with the paramagnetic system. Detection by optical techniques of microwave phonons is, apart from the ease of detection, of some advantage since signal to noise that can be obtained by high energy photon counting is superior to that usually obtained by conventional macroscopic microwave detection techniques.
