摘要：

We investigated the magneto-optical properties of diluted magnetic semiconductor Cd0.65-yMn0.35ZnyTe single crystals grown using a vertical Bridgman method. The Cd0.65-yMn0.35ZnyTe crystals with various Zn mole fractions have been grown in the zinc-blende structure and the band-gap energy was increased and the lattice constant was decreased showing inverse relationship with the band-gap energy with increasing Zn contents. The Faraday rotation was increased as Zn content is increased and the origin of the enhancement of the Faraday rotation in CdMnZnTe crystals can be explained in terms of the magnetization.
