Abstract
One-magnon inelastic light scattering in EuTe by thermal magnons belonging to both branches of the excitation spectrum is studied. The dependences of the magnon frequency and of the intensity of the scattered light on the magnetic field are measured. The contribution to the intensity of one-magnon light scattering from exchange mechanism, which is of decisive importance for strongly canted magnetic sublattices, is separated.
