Highly ordered arrays of sub-micrometer-sized coaxial cables consisting of fullerene tube sheaths and Ni nanowire cores, such as shown in the figure, are fabricated by combining a sol–gel technique with an electrodeposition process. The wall thickness of the tubular sheaths can be adjusted by varying the fullerene concentration and the immersion time. These composite nanostructures exhibit enhanced ferromagnetic behavior as compared to bulk nickel.
