Resonant magnetic scattering of linearly polarised soft X-rays from Fe-layers and Fe/C-multilayers

We report on scattering experiments in T-MOKE geometry performed at the Fe-2p absorption edge of an ex situ grown Fe layer and an Fe/C multilayer. We used linearly polarised synchrotron radiation and measured the reflected intensities upon reversal of the magnetisation perpendicular to the scattering plane. The asymmetry ratio A has been determined as a function of magnetic field strength, photon energy and angle of incidence. These data are discussed in terms of interference effects and the depth profile of the refraction index and are compared with calculations.
