We have observed Raman scattering from the antiferromagnet CsMnF3 over the temperature range from 5 to 300 °K. Of the 33 predicted Raman active normal modes, at low temperature, we have observed and identified 29, belonging to the A1g, E1g, and E2g representations of the space group D46h. At higher temperatures many of these lines broadened and shifted in energy from anharmonic interactions. Below the antiferromagnetic ordering temperature 53.5 °K, we have also seen Raman scattering from a two-magnon excitation located at 92.8 cm-1 at 5 °K. The energy of this line is consistent with the prediction of spin-wave modes calculated using previously determined exchange constants.
