Abstract

The comparative analysis of the electrochemical deposition of Ni and Ni-Fe nanowires (NWs) into ordered porous alumina templates is presented. The method developed allows for obtaining NWs of 50 ± 5 nm in diameter and 25 μm in length, i.e., with an aspect ratio of 500. XRD data demonstrate the polycrystalline nature of Ni and Ni-Fe in a face-centered cubic close-packed lattice. Both fabricated materials, Ni and Ni-Fe, have shown ferromagnetic properties. The specific magnetization value of Ni-Fe NWs in the alumina template is higher than that of the Ni sample and bulk Ni, also the Curie temperature of the Ni-Fe sample (790 K) is higher than that of the Ni sample one or bulk Ni.

摘要

本文介绍了镍和镍铁纳米线（NWs）在有序多孔氧化铝模板中的电化学沉积对比分析。所开发的方法能够制备出直径为50±5nm、长度为25μm的纳米线，即长径比为500。X射线衍射（XRD）数据表明，镍和镍铁在面心立方密堆积晶格中具有多晶性质。制备的镍和镍铁材料均表现出铁磁性能。氧化铝模板中镍铁纳米线的比磁化值高于镍样品和块状镍，而且镍铁样品的居里温度（790K）高于镍样品或块状镍。
