Nickel, cobalt and iron oxide nanotubes were obtained by atomic layer deposition (ALD) into the pores of alumina membranes. Initially, a metal oxide film was grown by the reaction of a precursor vapor of NiCp2 (nickelocene), CoCp2 (cobaltocene) or FeCp2 (ferrocene) with ozone, respectively. Subsequently, the metal oxide film was reduced in hydrogen atmosphere and converted to a metallic ferromagnetic phase with low-degree of surface roughness. In a similar manner, Fe3O4 films have also been… CONTINUE READING
