摘 要:In order to control the orientation of easy-axis of magnetic nanowires, Fe3O4 single crystal nanowires with easy-axis perpendicular to wire-axis were prepared successfully by means of a magnetic-field-induced method. Analysis of X-ray diffraction and electron diffraction pattern showed that there was a wide-angle deflection of easy-axis in the prepared Fe3O 4 nanowires. A high saturation magnetization (82 emu/g) of the Fe3O4 nanowires was achieved at room temperature. The benefits and mechanism of the deflection of easy-axis from its wire-axis in Fe 3 O 4 single crystal nanowires were discussed. The results are expected to broaden the magnetic properties of traditional ferrite nanowires.
