Magneto-optical properties of the diluted magnetic semiconductor p-type ZnMnO

Abstract We present a magneto-optical study of p -type Zn 1− x Mn x O diluted magnetic semiconductors (DMS) obtained by thermal oxidation Zn 1− x Mn x Te layers. Photoluminescence spectra were used to determine the “giant” Zeeman splitting and to estimate the exchange integrals N 0 (α−β)∼0.1 eV. This is an extremely small value for a II–VI DMS, and we discuss possible reasons for this effect.
