The deliberate control over the spatial arrangement of nanostructures is the desired goal for many applications as e.g. in data storage, plasmonics or sensor arrays. Here we present a novel method to assist the self-assembly process of magnetic nanoparticles. The method makes use of nanostructured aluminum templates obtained after anodization of aluminum disks and the subsequent growth and removal of the newly formed alumina layer, resulting in a regular honeycomb type array of hexagonally shaped valleys. The iron oxide nanoparticles, 20 nm in diameter, are spin coated onto the nanostructured templates. Depending on the size, each hexagon site can host up to 30 nanoparticles. These nanoparticles form clusters of different arrangements within the valleys, such as collars, chains, and hexagonally closed islands. Ultimately, it is possible to isolate individual nanoparticles. The strengths of magnetic interaction between particles in a cluster is probed using the memory effect known from the coupled state in superspin glass systems.
