Metal nanorod arrays and their magnetic properties

Large-area, highly uniform metal nanorod arrays (iron, cobalt, nickel) with variable diameters have been successfully synthesized by electrochemical deposition method using polycarbonate (PC) membrane template. By means of X-ray diffraction, scanning electron microscopy (SEM), transmission electron microscopy (TEM), vibrating sample magnetometer (VSM) at room temperature, their microstructures and magnetic properties were investigated. The mechanism of crystals nucleated and grown theories in metal nanorod arrays were also discussed.
