摘要：

The electronic as well as magnetic properties of GaxFe1-x films were studied by soft x-ray measurements. Using x-ray magnetic circular dichroism the Fe majority-spin band was found to be completely filled for x approximate to 0.3. With further enhanced Ga content, the Fe moment as well as the angular dependence of the x-ray magnetic linear dichroism decrease strongly, which we attribute to the formation of D0(3) precipitates. Moreover, the magnetocrystalline anisotropy drops significantly.
