Probing lateral magnetic nanostructures by polarized GISANS

While structural and magnetic lateral correlations in thin film materials can be investigated at the μmμm length scale by neutron off-specular scattering (OSS) with polarization analysis, they can also be investigated at the nm length scale by grazing incidence small-angle scattering of polarized neutrons (polarized GISANS). We exemplify this issue showing a combined OSS and GISANS study of the lateral correlations in a remanent polarizing supermirror.
