N2 - We report a unique approach to fabricating a large number of iron oxide nanowires from a Fe plate. This is realized with the aid of both oxidation (chemical reaction) and atomic migration (physical phenomenon). A polycrystalline Fe plate was prepared and its surface was oxidized in HNO 3 solution. Then, the plate was bent to introduce stress and heated at 600 °C for 3 h. A large number of nanowires with diameters of 40 ± 10 nm and lengths of 1.5 ± 0.7 μm were successfully obtained. On the other hand, there was no wire growth on a plate without oxide. From a structural analysis, the nanowires were found to be single-crystalline Fe 3O4.
