摘要：
Magnetic circular dichroism is used to investigate the evolution of ferromagnetism in the p-type magnetic semiconductor (Ga1-xMnx)As. Local Mn moments and holes produce two spectroscopically distinct contributions, whose properties reveal an antiferromagnetic Mn-hole alignment in the ferromagnetic state. These components are present in both metallic and insulating samples with different temperature and field dependences, suggesting that the holes play a mon active role in mediating the ferromagnetic exchange than in traditional RKKY systems.
