Abstract
We investigated the magneto-optical properties of diluted magnetic semiconductor Cd0.65-gamma Mn0.35Ni gamma Te single crystals grown using a vertical Bridgman method. This material crystallizes in the zinc-blende structure for values of gamma < 0.06. The fundamental enegy gap was increased and the lattice constant was decreased showing inverse relationship with the band gap energy with increasing Ni contents. The Verdet constant increased with increasing gamma, which is consistent with behavior of the magnetization. The Faraday rotation in Cd0.65-gamma Mn0.35Ni gamma Te crystals was increased as Ni contents was increased, which is due to the increasing of magnetization with Ni contents
