Abstract

Anodization of alloys containing Al, Ni, Co and Fe as main constituents is reported here for the first time for formation of thin film of self-organized magnetic nanoporous structure. Fluoride concentration, anodization potential and the amount of water in the ethylene glycol electrolyte are very critical parameters to produce the well-aligned nanostructure. Further, the presence of Al in the alloy to protect the ferrite nanostructure by controlling the selective dissolution of oxide layers of Ni, Co, Cu was essential.
