摘要
The field dependence of spin and orbital magnetic moments of Fe in L1 0 FePt magnetic thin films was investigated using X-ray magnetic circular dichroism (XMCD). The spin and orbital moments were calculated using the sum rules; it was found that the spin and orbital moment of Fe in L1 0 FePt films are ∼2.5 and 0.2 μ B , respectively. The relative XMCD asymmetry at Fe L 3 peak on the dependence of applied field suggested that the majority magnetic moment of L1 0 FePt films resulted from Fe. © 2006 Elsevier B.V. All rights reserved.
