采用溶胶-凝胶化学方法，以阳极氧化铝（AAO）为模板，成功地生长了高度有序的镍铁氧体纳米线。研究了凝胶的热分解和相演变，以确定合适的煅烧温度。X射线衍射和傅里叶变换红外光谱分析结果表明，在600 °C下煅烧可以得到单相的NiFe 2 O 4纳米线。无缺陷的NiFe_2O_4纳米线具有约600的高纵横比，表现出形状磁各向异性。
Highly ordered nickel ferrite nanowires were successfully grown via a sol–gel chemical route using an anodic aluminum oxide (AAO) template. The thermal decomposition of the gel and phase evolution were investigated to determine the appropriate calcination temperature. The X-ray diffraction and Fourier transform infrared spectroscopy results showed the single phase NiFe2O4nanowires can be achieved after calcination at 600 °C. Furthermore, the defect free NiFe2O4nanowires with the high aspect ratio of about 600 exhibited shape magnetic anisotropy.
