电化学沉积Fe单晶纳米线生长中的取向控制

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，［200］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200]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. 关键词： 磁性纳米线 电化学沉积 取向控制

Control of the preferred orientation in electrodeposited single-crystal Fe nanowires

Three different_structured Fe nanowires, including preferred orientations of 110],200] and morphology nanowires,were electrodeposited by a method of changing the pH value of the aqueous bath.And the 200]_preferred Fe nanowire was reported for the first time so far as we know.Magnetic properties of the three kinds of nanowires were measured by superconducting quantum interference devics(SQ UID) magnetometer.Compared with the 110] preferred nanowire array,the 200] preferred one has a high aspect ratio with improved anisotropy and coercivity.It is first time that the magnetization of Fe nanowire arrays with the crystal anis otropy and shape anisotropy in the same direction has been reported.
