Magnetic nanobelts of iron-doped zinc oxide

Abstract

Magnetic nanobelts of iron-doped zinc oxide were fabricated by vapor–phase transport using zinc oxide, iron oxide, and graphite as source materials. The nanobelts grew mainly along [101¯0] orientation and enclosed by ±(0001) and ±(1¯21¯0) surfaces. The measurements of x-ray diffraction, energy-dispersive x-ray spectroscopy, and high-resolution transmission electron microscopy demonstrated that iron was doped into the nanobelts. As a result, the nanobelts were magnetic.
