X-ray magnetic circular dichroism study on CeFe2
Abstract
X-ray magnetic circular dichroism at the Fe L2,3, Ce M4,5 and Ce L2,3 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 - 0.29μB (M5d = - 0.13μB, M4f = - 0.16μB) and a ratio for the 4f contribution langleLzrangle/langleSzrangle approx - 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.
