The article reviews the recent determination of the magnetic structures of an [Fe/Gd] 15 multilayer by the authors using resonant magnetic scattering of circular polarized x-rays at synchrotron sources.The specular reflections reveal that the 5.4-nm-thick Gd layers magnetize highly nonuniformly along the out-of-plane direction in both magnitude and azimuthal angle in the aligned and twisted states of the sample. The decay of the qx-scan magnetic diffuse scattering evidences much smoother magnetic interfaces than the charge interfaces.The qz-dependent difference diffuse peaks suggest the presence of rough magnetic interfaces within the Gd layers.
