FeNi alloy nanowires and nanotubes have been fabricated in the pores of the anodized aluminum oxide (AAO) templates by direct current electrodeposition with different potentials. The crystal structure and micrograph of FeNi alloy nanowires and nanotubes were characterized by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy, and the content was confirmed by energy dispersive spectrometry. The results indicate that there is a critical potential in the formation of nanowires and nanotubes. FeNi alloy nanowires and nanotubes both present the (111) preferred orientation, and the content of Fe is reduced with the decrease of electrodeposition potentials. The magnetic behaviors of FeNi alloy nanowires and nanotubes with different ratios are investigated. The coercivity of FeNi alloy nanowires and nanotubes exhibits disparate behavior, which may attribute to their grain size and distinctive structure.
