Magnetic nanocrystals organized in chain‐like structures behave as nanowires with a shape anisotropy induced by the structuration of the sample. This is valid for various types of magnetic nanomaterials. Furthermore, the coating of nanocrystals plays a major role in the mesoscopic structure of the film. γ‐Fe 2 O 3 nanocrystals are used as a mask to reproduce the mesoscopic structure on a silicon wafer.
