High aspect ratio Ni nanowires (NWs) and nanotubes (NTs) were electrodeposited inside ordered arrays of self-assembled pores (approximately 50 nm in diameter and approximately 50 μm in length) in anodic alumina templates by a potentiostatic method. The current transients monitored during each process allowed us to distinguish between NW and NT formation. The depositions were long enough for the deposited metal to reach the top of the template and form a continuous Ni film. The overfilling process was found to occur in two steps when depositing NWs and in a single step in the case of NTs. A comparative study of the morphological, structural, and magnetic properties of the Ni NWs and NTs was performed using scanning electron microscopy, X-ray diffraction, and vibrating sample magnetometry, respectively.
高纵横比的镍纳米线 (NWs) 和纳米管 (NTs) 是通过恒电位法在阳极氧化铝模板中的自组装孔（直径约为 50nm，长度约为 50μm）的有序阵列中电沉积的。在每个过程中监测到的电流瞬变使我们能够区分 NW 和 NT 的形成。沉积时间足够长，使得沉积的金属能够到达模板的顶部并形成连续的 Ni 膜。当沉积 NWs 时，发现过填充过程分两步进行，而在沉积 NTs 时则一步进行。使用扫描电子显微镜、X 射线衍射和振动样品磁强计分别对 Ni NWs 和 NTs 的形貌、结构和磁性能进行了比较研究。
