【 摘 要 】

Influence of disorder in the concentration of magnetic Mn2+ ions on the ferromagnetic phase transition in diluted (III,Mn)V semiconductors is investigated analytically. The regime of small disorder is addressed, and the enhancement of the critical temperature by disorder is found both in the mean-field approximation and from the analysis of the zero-temperature spin stiffness.
