Fabrication of FeCo / Cu / Au multilayer nanowires in the alumina template by electrodeposition method: growthrate of FeCo, Cu and Au layers

Array of gold-iron/cobalt-copper multilayer nanowires have been synthesized with a length of 1100 nmand a diameter of 70 nm. Arrays of multilayer nanowires were grown using direct currentelectrodeposition (DC) in a porous anodic aluminum oxide (AAO) template. Anodic aluminum oxidetemplate with a thickness of 80 μm, as a template for making nanowires array using two-step anodizingmethod, is made of pure aluminum foil with oxalic acid. According to the SEM results, the growth rateof different layers and their thickness were determined. The growth rate of FeCo, Cu and Au layers inthe template with pore diameters of 70 nm was determined to be 0.3, 0.61 and 0.33 nm / sec,respectively.
