Abstract
Raman scattering measurements are performed on Mn‐xCd1‐xTe mixed crystals, in the concentration range x = 0 to x = 0.5. The first‐order spectra show a “two‐mode” behaviour for the long‐wavelength optical phonons, which can be explained using the theoretical REI model. The rest of the spectra, confirmed by infrared absorption measurements, is tentatively interpreted in terms of two‐phonon processes and presumably one‐acoustic‐phonon disorder‐induced modes, resulting from mass disorder.Keywords
