Abstract

The field dependence of the magnetization in epilayers of the diluted magnetic semiconductor Ga1-xMnxAs for 0.0135<x<0.083 was discussed. It was suggested that the spin state of the nonferromagnetic Mn spins were energetically well separated from the ferromagnetism of the bulk of the spins. The analysis showed that Hc decreased with increasing Mn concentration as predicted theoretically.
