| Abstract: | The first order Raman scattering in various phases of EuSe and EuTe was theoretically studied. The Raman lines which depend on spin structures are caused via the spin-dependent polarizabilities. The phonon dispersion relations of the crystals were calculated on the breathing shell model. The Stokes shifts and intensities of the Raman lines, and their polarization selection rules obtained from the present theory are in good agreement with experiments. |
