采用两步电沉积法成功制备了Ni/Fe壳/核有序纳米电缆阵列。首先，在阳极氧化铝（AAO）模板的纳米孔中电沉积镍（Ni）纳米管。然后以AAO/Ni纳米管复合膜为二次模板，在Ni纳米管中沉积存款Fe纳米线。用扫描电子显微镜（SEM）和透射电子显微镜（TEM）对纳米电缆的形貌和微观结构进行了表征。通过X射线衍射（XRD）证实了纳米电缆的化学组成。磁化强度测试表明，Ni/Fe纳米电缆阵列的剩磁比分别低于Ni纳米管和Fe纳米线阵列。
Ordered Ni/Fe shell/core structured nanocable arrays were successfully fabricated by a two-step electrodeposition process. Firstly, nickel (Ni) nanotubes were prepared by electrodeposition in nanoporous of anodic aluminum oxide (AAO) template. Then the AAO/Ni nanotube composite membrane was used as a secondary template to deposit Ferrum (Fe) nanowires into Ni nanotubes. The morphology and microstructure of the nanocables was characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The chemical composition of the nanocables was confirmed by X-ray diffraction (XRD). Magnetization measurements revealed that Ni/Fe nanocable arrays have a lower remanence ratio than Ni nanotube and Fe nanowire arrays respectively.
