Abstract
We present the first theoretical study of the electronic properties of superlattices formed from semimagnetic semiconductors. We explicitly consider the Cd0.8Mn0.2Te/Cd0.7Mn0.3Te superlattice system. We show magnetic field splittings both including (zero spin temperature) and neglecting (high spin temperature) the exchange interaction. We find that the exchange interaction dominates the magnetic effects. We present calculations of the derivative of the superlattice band gap with magnetic field as a function of the superlattice layer thickness. We show calculations of the change in superlattice band gap with magnetic field for several magnetic fields as a function of temperature.
