The electrodeposition of highly ordered macroporous films of cobalt with regular arrays of spherical pores of the diameters 200, 550, 600, 750 and 1000 nm was carried out into the interstitial spaces of a template formed by polystyrene latex spheres. The spheres were self-assembled on flat gold electrodes of 1 cm2 surface area to produce a highly periodic, hexagonal close packed, interconnected network of monodisperse spherical pores within the metal film. The size of pores was determined by the diameter of the polystyrene latex particles used to prepare the template. The nanostructure of the films was studied by the scanning electron microscopy. Magnetic studies of the films were carried out with an Aerosonic 3001 vibrating sample magnetometer. The nucleation and the growth mode of cobalt were investigated via a chronoamperometry study.
