Abstract

We present absolute values for the complete set of magneto-optical constants around the ${Gd}_{4, 5}$ and Fe $L_{2, 3}$ dipole resonances as obtained from measurement of the polarization dependent photoabsorption cross sections and Kramers-Kronig transformation. The results are verified by comparing the resulting resonant scattering factors with the resonant magnetic scattering from a stripe domain lattice, showing an excellent agreement for both the circular and linear dichroic contributions.
