Abstract
We present our first theoretical study of the electronic properties of superlattices formed from semimagnetic semiconductors. Both Cd0.8Mn0.2Te/Cd0.7Mn0.3Te and Hg0.95Mn0.05Te/ Cd0.78Mn0.22Te systems are considered explicitly. Magnetic field splittings are calculated with and without the exchange interaction. We find that the exchange interaction dominates the magnetic effects in the wide-gap Cd0.8Mn0.2Te/Cd0.7Mn0.3Te system while the Landau level shift is also important in the Hg0.95Mn0.05Te/ Cd0.78Mn0.22Te system. We present calculations of the superlattice band-gap variation with temperature and its derivative with magnetic field as a function of the superlattice layer thickness. Variation of the band offset in determining the values of the various quantities is examined.
