Self‐organization of nanoparticles into hierarchical assemblies is very important for the development of “bottom‐up” approaches in nanotechnology. Porous silicon can be used as a substrate to prepare fractal‐like magnetite nanoparticle assemblies, which add a new dimension to nanoscale spin electronics as each small portion of the fractal can be viewed as a reduced‐scale replica of the whole (see figure).
