Abstract
Ni nanostructures of different geometries as spheres, ellipsoids or wires, as well as with various spatial distributions are deposited electrochemically within the pores of porous silicon (PS). The hybrid material offers magnetic properties which depend on the morphology of the composite and the interactions between the metal precipitates, respectively. So the magnetic behavior can be correlated with the process parameters. On the one hand the morphology of the PS template determines the coupling of the metal structures located within adjacent pores and on the other hand the spatial distribution and geometry of the deposits influences the interaction of nanostructures within one pore. Thus also the anisotropy of the nanocomposite can be modified not only by the shape of the ferromagnetic nanostructures but also by their spatial density within the oriented pores of the porous matrix.
