Arrays of Co nanowires with different lengths and diameters have been prepared by electrodeposition into nanopores of alumina and polycarbonate membranes. The dependence of the coercivity and remanence of the arrays as a function of the length, the electrodeposition potential, and the electrolytic bath pH of the nanowires has been experimentally investigated through hysteresis curves performed in a VSM (vibrating sample magnetometer) and a SQUID (superconducting quantum interference device).
