Co fine wires were produced by both AC-electrodeposition (ED) and DC-ED. It was found that the hcp structures with different orientation were realized according to fabrication conditions. The coercive force of 2100 Oe was obtained for DC-ED wires. Co particles were synthesized by the alternating ED of Cu and Co in the pores with using a single electrolyte based on CoSO_4 and CuSO_4. The deposition voltage was pulse modulated to provide deferent deposition potentials, -1.40V for Co and -0.65V for Cu. Coercive force ranges between 0 to 1000 Oe and depends on the duration of Co deposition. Superparamagnetism was observed in a case of 1 sec deposition of Co and the length of wires was estimated to be 7 nm.
