摘要：

The s,p-d exchange interaction of p-type Ga1-xMnxAs (x<0.05) epilayers is investigated by means of magnetoabsorption. The observed ferromagnetic-type splitting of fundamental absorption edge is explained by antiferromagnetic p-d exchange interaction, taking into account the Moss-Burstein effect, resulting from high hole concentration.
