Improvement of Magnetic Properties of CoZn Nanowire Arrays through Annealing Procedure

CoZn nanowire arrays were fabricated by ac pulse electrodeposition into porous alumina templates. Theeffects of various off time between pulses and annealing procedure were investigated. Increasing the off, increased the Co content due to electroless phenomenon. Adding off time also increased the magnetization, coercivity and squareness of the nanowires. Annealing improved the magnetic properties and a coerrcivity 2175 Oe was obtained. X ray diffractiometery showed almost amorphous phase in as prepared nanowire arrays. Annealing improved the crystallinity of the samples.
