| 中文摘要 | Highly ordered La0.62Pb0.38MnO3 nanowire arrays are successfully fabricated using an improved sot-gel template method. The x-ray diffraction and transmission electron microcopy results reveal that the nanowires are polycrystalline with uniform diameter around 50 nm. Magnetic measurement indicates that the ferromagnetic transition temperature T-C of the nanowires is around 308 K, which is lower than that of the corresponding bulk material. The nanowire arrays demonstrate the perpendicular magnetic anisotropy as a result of shape anisotropy and enhanced coercivity compared with bulk materials and the temperature dependence of the saturation magnetization exhibits a T-1.25 behaviour. The growth mechanism of the nanowires is also briefly discussed. |
