(110) Orientation growth of magnetic metal nanowires with face-centered cubic structure using template synthesis technique

A template-assisted assembly technique has been used to synthesize magnetic metal nanowire arrays. Fe, Co, Ni nanowires are fabricated using direct-current electrodeposition in the pores of anodic alumina membranes. The morphology and the crystal structure of the samples are characterized by field-emission scanning electron microscopy, transmission electron microscopy, and X-ray diffractometer. The results indicate that Fe, Co, and Ni nanowires all have face-centered cubic (FCC) structure and a preferred orientation along the [110] direction. The ability to prepare well-defined orientation growth of magnetic metal nanowires with FCC structure opens up new opportunities for both fundamental studies and nanodevice applications.

Research Highlights► Fe, Co, and Ni nanowires are fabricated in the AAM templates by electrodeposition. ► Well-defined orientation growth of the nanowires with FCC structure were investigated. ► The electrodeposition parameters affect the crystal structure and growth orientation.
