Template-assisted electrodeposition has been used to fabricate arrays of polyethylene glycol polymer (PEG) coated ferromagnetic nickel nanowires.  During the process, metal and polymer were co-deposited into the pores of an anodic alumina membrane (AAO). The formation of the PEG (shell) with the Ni (core) occurs when PEG adsorbs on the pore walls followed by deposition of nickel metal along the pore channel. Unlike conventional nickel nanowires, polymer-coated ones have a tendency to show greater resistance to breakage and less of a tendency to agglomerate after dissolution of the template. The latter becomes especially significant in looking at magnetic hysteretic properties as a function of wire array orientation � free standing polymer coated nanowires more effectively retain their magnetic properties.
