Abstract

Abstract:

Single-crystal Ni nanowire arrays were prepared by employing the porous AAO template by using the electrodeposition technique at a constant current of 2.0 mA/cm². The morphology and microstructure of Ni nanowire arrays were studied by SEM, TEM and XRD techniques. The magnetic properties of the single-crystal Ni nanowire arrays were investigated by VSM. The results reveal that the single-crystal Ni nanowire arrays show a perpendicular magnetic anistory and have a preferential magnetic orientation along the wire axis. The magnetic properties of the single-crystal Ni nanowire arrays are better than those of polycrystal nanowire arrays.
