Abstract: Magnetic circular dichroism (MCD) in X-ray absorption has been measured at the L 2, 3 edges of Fe in ex-situ grown Fe and Fe 0.50 Co 0.48 V 0.02 films by means of the transmission method. A new approach is developed for fitting the observed transmittance, which describes the resonance lineshapes as (generalized) Fano profiles. Analytical integration of each single resonance allows a more reliable determination of the orbital and spin magnetic moments based on the MCD sum rules. The results are consistent with an increase of the Fe spin and orbital magnetic moment in Fe-Co alloys as obtained by other experiments and band structure calculations.
