摘要：

Circular magnetic x-ray dichroism is studied at the L edges of the 3d transition metal series (Cr, Mn, Fe, and Co) as impurities in a nickel host, using partial fluorescence yield to monitor the absorption. While the latter 3d metals Mn, Fe, and Co couple ferromagnetically to the Ni host, Cr is found to couple antiferromagnetically. Using a sum rule derived within an atomic description we obtain values of the spin magnetic moment of the impurities, which are in good agreement with calculations.
