Synthesis and Characterization of Magnetic Alloy Nanowire Arrays

ORAL

Abstract

We report the synthesis and characterization of ordered arrays of cobalt-nickel alloy nanowires electrodeposited into the pores of anodic alumina templates (AAO). Controlled diameters, lengths and compositions of these alloys were obtained by varying the pore sizes and electro-deposition conditions. The structural and magnetic properties of the samples were investigated using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM). We also present the effect of the compositional ratio of cobalt and nickel on the magnetic properties of the nanowires.
