[Phys. Rev. Lett. 61, 1245 (1988)]. The photon-energy dependence of firstand second-order magnetic satellites allows a straightforward identification of circular and linear dichroic contributions. A direct comparison to magnetic neutron scattering demonstrates the potential of the method for studies of complex magnetic structures in ultrathin films and highly diluted materials.
