Using polarized neutron reflectometry, the magnetic proximity effect in epitaxial bilayer heterostructures comprising ferromagnetic La0.7Sr0.3MnO3 and multiferroic orthorhombic YMnO3 layers has been investigated.

The presence of ordered nanostructures (nearest-neighbour ordering) is reported in self-organized Co nanopillar-like structures separated by Au spacers, attractive for applications in magnetic storage devices. Most interestingly, a strong dependence of the superparamagnetic blocking temperature on the degree of vertical correlation in the stack is found, which indicates a collective behaviour of individual clusters in the nonmagnetic Au matrix.

The growth of Fe on a mesoporous structure of titania anatase template has been investigated. The lateral and longitudinal correlation of the Fe layers as a function of thickness demonstrate the impact of the deposition kinetics on the physical properties of supported islands in the nanometric regime. Three different stages of growth were identified, characterized by different correlation lengths and magnetic behaviors in each regime.
