Soft x-ray resonant magneto-optical constants at the Gd M 4,5 and Fe L 2,3 edges

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.
