III Investigations of ferromagnetic alloy films by XMCD1. By using XMCD and SQUID magnetometry, the spin and orbital moments of Fe and Co in the Co_(0.9)Fe_(0.1)(50nm) are studied. Compared with single-element film, the spin moment of Co remains constant while that of Fe reduced from 1.98 to 1.63μB. The contributions of different elements in the film is, m_ : m_ - 10.5 : 89.5. The average magnetic moment (1.90μB) determined by XMCD is in agreement with that (1.82μB) obtained from SQUID measurements.
