In the past years a demand for new types of materials with different structures and specific physical properties for miniaturized devices, like MEMS and micro-electronics, is increasing. The nanowire arrays seem to have a large potential for a variety of applications. The nanowire of Co, Fe and FeCo alloy were prepared by the electrodeposition process into the alumina oxide membrane (AAO). AAO's were prepared by the two step anodizing process in oxalic acid solution. The influence of the electrolyte composition, electrodeposition parameters and superimposition of the external magnetic field during the deposition was studied. The effect of above parameters on the nanowire properties were determined by means of XRD, TEM, SEM, VSM and SQUID techniques. It was found that the properties of the deposited wires could be tuned by the preparation parameters. Especially the magnetic properties were affected, which are known to be very sensitive on the preparation conditions.
