ResumoExperiments have been carried out to determine the anti-Stokes and Stokes spectra for one-magnon Raman scattering from FeF2 in its antiferromagnetic phase. It is found that the anti-Stokes-Stokes intensity ratio differs considerably from the usual thermal factor exp (- ħω/kT), and this is analysed theoretically in terms of quadratic magneto-optical coupling.
