| Abstract: | In the present study, the single-crystal Ni nanowire arrays with a preferred growth along the 110] direction have been prepared by the deposition of Ni into the alumina template with nanopores at a current density of 2.0 mA/cm2. The single-crystal Ni nanowire arrays show a magnetic anisotropy with the easy axis parallel to the nanowires and an enhanced coercivity as compared with the polycrystalline Ni nanowire arrays. A large coercivity of 1110 Oe together with a high remanence Mr = 0.92Ms is observed for 15-nm diameter single-crystal Ni nanowire arrays. The preferred growth mechanism of the single-crystal nanowires is briefly discussed. |
