摘要
Curie temperatures (T-C) for Mn-doped GaN, GaP, GaAs and GaSb are calculated from first-principles by using a mapping on the Heisenberg model in the mean field approximation. Analysing concentration dependences of T-C as a function of the Mn concentration c, exchange interactions in diluted magnetic semiconductors are discussed. (C) 2003 Elsevier B.V. All rights reserved.
