ABSTRACT
Photoluminescence of quaternary cubic Zn0.1Cd0.89Mn0.01Te and wurtzite Cd0.99Mn0.01Se0.3Te0.7 semimagnetic semiconductors was investigated. Measurements were performed at the temperature of T=2K and magnetic field B=0–5T. The cubic sample was studied in Faraday configuration. Two lines were observed. By comparison to magnetoreflectivity data they were identified as the free exciton and the exciton bound to neutral acceptor. The wurtzite sample was studied in Voigt configuration. Three lines were observed. Two lines with energy lower than energy of the free exciton in magnetoreflectivity were identified as the free exciton and the exciton bound to neutral acceptor. Third line with the energy higher than free exciton was interpreted as the optical transition of carrier trapped on the fluctuation of the composition.
