  We present a synchrotron-based X-ray scattering technique which allows
disentangling magnetic properties of heterogeneous systems with nanopatterned
surfaces. This technique combines the nmrange spatial resolution of surface
morphology features provided by Grazing Incidence Small Angle X-ray Scattering
and the high sensitivity of Nuclear Resonant Scattering to magnetic order. A
single experiment thus allows attributing magnetic properties to structural
features of the sample; chemical and structural properties may be correlated
analogously. We demonstrate how this technique shows the correlation between
structural growth and evolution of magnetic properties for the case of a
remarkable magnetization reversal in a structurally and magnetically
nanopatterned sample system.
