摘要：

X-ray magnetic circular dichroism at the Fe L-2,L-3, Ce M-4,M-5 and Ce L-2,L-3 absorption edges of CeFe2 are reported. Application of the sum rules yields both the magnitude and the direction of the magnetic contributions (Fe 3d, Ce 5d and Ce 4f) to the total moment in CeFe2. A total Ce magnetic contribution of -0.29 mu(B) (M-5d = -0.13 mu(B), M-4f = -0.16 mu(B)) and a ratio for the 4f contribution [L-z]/[S-z] approximate to -1 are found, which confirms that the 4f states are highly hybridised in CeFe2. These results are in good agreement with previously published LSDA calculations.
