文摘We report here the acoustic local mode and TA band mode for the lattice vibration of the mixed crystals Cd_(1-x)Mn_(x)Te as observed by very far infrared spectra.The occurence of the acoustic local mode and the weakly optical activity of TA mode induced by crystalline-mixing are discussed in light of the defect lattice dynamics.
