Abstract :
In this paper, an experimental study on both the electrolytic growth and the magnetic properties of cobalt nanowires is presented. The wires were electrodeposited into the pores of track-etched polymer membranes, having a diameter ranging from 80 up to 250 nm depending on the size of the pores. The filling of the pores was monitored combining the measurement of the electrolytic current-time curves with atomic force microscopy imaging (AFM). After dissolving the membranes, the magnetic domain structure of isolated nanowires was visualized by means of magnetic force microscopy (MFM) showing a multidomain pattern. The results are analyzed considering that the c axis of the HCP-Co crystallites is mainly perpendicular to the wire axis
