Arrays of Nickel Nanowires

The arrays of nickel nanowires have been produced by electro-deposition of nickel into the pores of porous alumina membranes. The membrane has been resolved by chemical etching and free standing nanowires perpendicular to a substrate have been obtained. Due to their ferromagnetic properties, the nanowires have possible applications in high density magnetic recording media. The picture shows a cross section view of the nickel nanowire array.
