Magneto-optical properties in diluted magnetic semiconductors Cd0.65−yMn0.35NiyTe single crystals

Abstract We investigated the magneto-optical properties of diluted magnetic semiconductor Cd 0.65− y Mn 0.35 Ni y Te single crystals grown using a vertical Bridgman method. This material crystallizes in the zinc-blende structure for values of y y , which is consistent with behavior of the magnetization. The Faraday rotation in Cd 0.65− y Mn 0.35 Ni y Te crystals was increased as Ni contents was increased, which is due to the increasing of magnetization with Ni contents.
