Abstract

NiCo/Cu multilayer nanowires have been successfully fabricated by a pulse electrodeposition technique using anodic aluminum oxide templates, and their chemistry, crystal structure and
magnetic properties characterized at the nanoscale. It was found that each individual nanowire
had a regular periodic structure. The NiCo/Cu nanowires also displayed a continuous
morphology, smooth surface and polycrystalline fcc structure. EDX elemental mappings
confirmed the presence of nickel, cobalt and copper, which appear clearly with a periodic
distribution throughout the samples. Both the NiCo and Cu layers were polycrystalline and the
average length of the interlayers between NiCo and Cu layers was approximately 3–4 nm. The
NiCo/Cu nanowire arrays had an easy axis parallel to the length of wire and exhibited a
curling magnetization reversal mechanism. This study highlights the basis morphological,
structural and chemical information for NiCoCu/Cu multilayer nanowires, which is critical for
their applications in nanodevices and nanoelectronics.
