Abstract
Abstract Ferromagnetic–nonmagnetic heterogeneous ternary alloy Co–Ni–Pb nanowire arrays having composition, Co, 15 atom%; Ni, 45 atom%; Pb, 40 atom%, were successfully fabricated by alternating current (AC) electrodeposition into nanoporous alumina templates. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) observations revealed that the Co–Ni–Pb nanowries were polycrystalline with uniform diameters of around 20 nm and lengths up to several micrometers. Magnetic measurements showed that the coercivity of the samples increased with the annealing temperature up to 550 °C and reached a maximum (1020 Oe).
