利用电化学沉积方法 ,发现了一种能够动态地控制铁纳米线生长方向的沉积方法 ,利用该方法沉积了包括[110 ]取向 ,[2 0 0 ]取向及非晶态三种结构和取向的一维Fe纳米线阵列 .对于三种纳米线阵列 ,测量了它们的磁特性 ,分析发现具有 [2 0 0 ]择优取向纳米线阵列的方形度 ,各向异性特性和矫顽力都比 [110 ]取向阵列有很大的改善 Using electrochemical deposition method, we found a deposition method that can dynamically control the growth direction of the iron nanowires. With this method, three kinds of structures and orientations including [110] orientation, [200] orientation and amorphous state were deposited One-dimensional Fe nanowire arrays. For three nanowire arrays, their magnetic properties were measured and the squareness, anisotropy, and coercivity of the [200] preferred orientation nanowire arrays were found to be better than [110 Orientation arrays are greatly improved
