Abstract

A series of Ga1-x Mnx As layers with high Mn compositions x (=0.075-0.200) has been grown and investigated. Magnetization, magnetotransport, and magneto-optical properties reveal that the layers have single ferromagnetic phase as in the case of typical (Ga,Mn)As. The authors also describe the variation of magnetic anisotropy with x and the effect of low temperature annealing on Curie temperature.
