Preparation of the heterogeneous nanobrush based on the AAO templates and magnetron sputtering. (a) A regular AAO template was achieved by two-step oxidation; (b) Fe, Co, or FeCo alloy nanowires were deposited by alternating current; (c) a nanoscale film covered the surface by magnetron sputtering (the AAO template was hidden in this sketch).
