Electrochemically synthesized binary alloy FeNi nanorod and nanotube arrays in polycarbonate membranes

The binary alloy Fe41Ni59 cylindrical nanorods and Fe32Ni68 cylindrical nanotubes have been successfully synthesized by electrochemical deposition in porous polycarbonate membranes. The length and diameter of as-synthesized Fe41Ni59 nanorods and Fe32Ni68 nanotubes are 6–7 μm and 200 nm, respectively. The magnetic properties of the as-synthesized Fe41Ni59 nanorod and Fe32Ni68 nanotube arrays have been studied. From hysteresis loops, the nanorod and nanotube arrays have anisotropy with the easy magnetization along the direction of the arrays.
