Abstract

Results of two-magnon Raman scattering in ${Cd}_{x}$ ${Mn}_{1 - x}$ $F_{2}$ mixed crystals are presented for concentration 0≤x≤0.1 in the temperature range 9 K≤T≤70 K. The temperature and composition dependencies of the spectra are interpreted in the Ising cluster model approximation. This theory gives linewidths, line shapes, and frequencies that are in good agreement with experiment. Exchange integrals with the next-nearest magnetic neighbors are evaluated for all the samples investigated.
