Monte Carlo study of ferromagnetism in (III,Mn)V semiconductors

Schliemann, John ; König, Jürgen ; MacDonald, A. H.



Abstract

We report on Monte Carlo studies of the kinetic exchange model for (III,Mn)V ferromagnetic semiconductors in which S=5/2 local moments, representing Mn2+ ions, are exchange coupled to band electrons. We treat the Mn2+ spin orientations as classical degrees of freedom and use the hybrid Monte Carlo algorithm to explore thermodynamically important Mn spin configurations. The critical temperature Tc ...
