摘要：

X-ray magnetic circular dichroism has been measured at the Fe K-edge in ferrimagnetic Ho-iron-garnet. By measuring the dependence of dichroic spectrum on the angle between magnetization direction and the X-ray wave vector, dipolar and quadrupolar contributions are extracted on the basis of the recently developed theory. The pre-peak structure is mainly assigned to the 1s-3d transitions dipole-allowed by the charge transfer from O 2p to 3d-states of Fe3+ ion in tetrahedral site.
