Abstract

One-dimensional magnetic nanowires are generally thought to show fine axial magnetism for their special high aspect ratio of the shape. However, the magnetic nanowire arrays fabricated by DC electrodeposition in template pores always show a low squareness in parallel to the nanowire direction. We developed two general and simple methods to improve the squareness of the as-fabricated Ni nanowire arrays parallel to the nanowire direction. The nanowires are found to be polycrystalline. The magnetism of the nanowire is also analyzed based on the microstructure.

摘要

一维磁性纳米线通常因其特殊的高形状纵横比而被认为具有良好的轴向磁性。然而，通过直流电沉积在模板孔中制备的磁性纳米线阵列在与纳米线方向平行时总是表现出低矩形比。我们开发了两种通用且简单的方法来提高所制备的镍纳米线阵列在与纳米线方向平行时的矩形比。发现纳米线是多晶的。还基于微观结构对纳米线的磁性进行了分析。
