We report on a structural and magnetic investigation of Fe/δ-Mn multilayers. In situ LEED shows that Mn grows epitaxially on BCC Fe with a good crystallinity up to 30 Å. Reflectivity and small-angle diffuse scattering of synchrotron radiation on Fe/Mn/Fe sandwiches reveal sharp interfaces with correlated roughness. From MOKE measurements, evidence for non-collinear coupling between the Fe layers was found for Mn spacer thicknesses below 13 Å. With polarized neutron reflectometry and high-angle neutron diffraction we could not detect any sign of magnetic order inside the Mn layers.
