摘要：

The Raman scattering in a II-VI quaternary compound (Cd1-x-yZnxMnyTe) exhibits zone-center optical phonons whose frequencies vary with composition in a manner amenable to an extension of the modified random-element isodisplacement model. As a member of diluted magnetic semiconductors, Cd1-x-yZnxMnyTe exhibits the characteristic large magnetic-field-dependent redshift of the excitonic photoluminescence, the Raman-electron paramagnetic resonance of Mn2+, and an evidence of the Raman-antiferromagnetic resonance.
