摘要：

Using density-functional theory, we study the magnetic stability of the Ga1-xMnxN alloy system. We show that unlike Ga1-xMnxAs, which shows only ferromagnetic phase, Ga1-xMnxN can be stable in either ferromagnetic or antiferromagnetic phases depending on the alloy concentration. The magnetic order can also be altered by applying pressure or with charge compensation. A band-structure model is used to explain these behaviors. (c) 2005 American Institute of Physics.
