Comparison of data recorded at BL 5.2 and using the SX 700 III beamline at BESSY I for the dichroic parts of the thicker (some 20 ML) Fe, Co and Ni thin films. All spectra are shown with the minimum of dichroic intensity set arbitrarily to an energy of 0 eV on a relative energy scale. An offset of 100 arbitrary units is applied for Co and 200 for Fe, to enable a better comparison to be made. As the EPU delivers light almost fully circularly polarized, scaling factors for the SX 700 data have been used (see text). Clear differences can be observed in the s-state spectral region between the two d-state white lines. The differences observed in the widths of the white lines are attributed partly to the different degrees of circular polarization of the two sources in combination with the exchange splitting of the final states (see text).
