Abstract

Calculations are presented for the temperature dependence of one-magnon light scattering from two-sublattice ferrimagnets. The scattering Hamiltonians is taken to include linear and quadratic magneto-optical coupling terms. This represents an extension of recent work in which only the linear magneto-optical coupling was considered in calculating the scattered intensities for ferrimagnets. The theory is applied to YIG for which the quadratic magneto-optical coupling is known to be important, and comparison is made with the available light scattering data.
