Structural and Conductive Characteristics of Fe/Co Nanotubes

Abstract

The properties of Fe/Co nanotubes, which were fabricated by the method of electrochemical template synthesis, are studied. It is shown that the atomic ratio between the metals in the nanotubes shifts in the direction of cobalt with increasing potential difference during their synthesis; the geometric parameters of nanotubes, in particular, the wall thickness, also vary. Using the X-ray diffraction analysis, it was found that an increase in the concentration of cobalt in the crystal structure of nanotubes leads to a decrease in the interplanar distance and an increase in the conductivity.
