The quantitative analysis of magnetic x-ray scattering from thin Ho-metal films at the lanthanide M5 resonance reveals magnetic scattering length fmag up to 200r0, i.e. of the same order of magnitude as theoretically predicted. The photon-energy dependence of first- and second-order magnetic satellites allows a straightforward identification of circular and linear dichroic contributions to the scattering length. In a few examples we demonstrate the potential of the method for studies of complex magnetic structures in ultrathin films.
