The atomic layer deposition (ALD) technique, featured with self-limiting surface reactions, is ideal for the synthesis of  nanotubes due to its precise control of the thickness at the monolayer level, excellent step coverage and conformal deposition on high aspect ratio structures.

Highly ordered arrays of magnetic nanowires produced inside the pores of anodic alumina membranes by electrochemical deposition have been the focus of intense research. The high ordering, together with the magnetic nature of the wires, gives rise to outstanding cooperative properties different from the bulk and even from film systems.

Magnetic antidot arrays are groups of ordered holes created on a continuous magnetic film. They are being intensively investigated as candidates for high-density storage media, magnonic crystals with potential application in microwave devices, magnetically-active plasmonics, and lately for magnetic biosensing applications.
