Abstract

We report the synthesis and characterization of ordered multiferroic BiFe O3 (BFO) nanotube arrays. BFO nanotubes with diameters of about 250 nm and lengths of about 6 μm were fabricated by means of a sol-gel method utilizing nanochannel alumina templates. After postannealing at 700 °C, the BFO nanotubes exhibited a polycrystalline microstructure, and x-ray diffraction and transmission electron microscopy study revealed that they are of a perovskite crystal structure. Significant ferroelectric and piezoelectric characteristics of BFO nanotubes have been demonstrated by means of piezoresponse force microscopy measurement.
