摘要：
We present a magneto-optical study of p-type Zn1-xMnxO diluted magnetic semiconductors (DMS) obtained by thermal oxidation Zn1-xMnxTe layers. Photoluminescence spectra were used to determine the "giant" Zeeman splitting and to estimate the exchange integrals N-0(alpha-beta) similar to 0.1 eV. This is an extremely small value for a II-VI DMS, and we discuss possible reasons for this effect. (c) 2006 Elsevier Ltd. All rights reserved.
