Domain Shapes and Superlattices Made of Cobalt Nanocrystals

Abstract

3D organization of magnetic nanoparticles has until now only been observed on a small scale. In this communication, the formation of large-scale 3D superlattices of cobalt nanocrystals (see Figure) is reported, in which the degree of organization is shown to be highly dependent on the strength of magnetic field applied during deposition.
