Inter-impurity and impurity-host magnetic correlations in semiconductors with low-density transition-metal impurities

Yoshihiro Tomoda, Nejat Bulut, Sadamichi Maekawa

Experiments on (Ga,Mn)As in the low-doping insulating phase have shown evidence for the presence of an impurity band at 110 meV above the valence band. The motivation of this paper…
