The structure and anisotropic magnetization of One-dimensional (1D) Nd/Co/PA66 coaxial nanocables prepared by a low cost physical infiltration and electrodeposition methods are investigated. The preparation of Co nanotubes, Co/PA66 two-layer nanotubes and Nd/Co/PA66 three-layer nanocales is described, respectively. The structure, chemical composition and magnetic properties of various nanomaterials were investigated. The results show that the magnetic properties were affected by the rare earth metal Nd and the structural properties. The residual magnetization ratio of Nd/Co/PA66 nanocables is the biggest due to the synergistic effect of Nd and Co. In addition, the magnetization processes of the nanostructure were discussed in detail. We believe that these methods may provide an idea for ferromagnetic alloys and permanent magnet material and suitable for future applications in perpendicular recording media.
研究了通过低成本物理浸润和电沉积方法制备的一维（1D）钕/钴/聚酰胺66（Nd/Co/PA66）同轴纳米电缆的结构和各向异性磁化。分别描述了钴纳米管、钴/聚酰胺66双层纳米管和钕/钴/聚酰胺66三层纳米电缆的制备过程。研究了各种纳米材料的结构、化学成分和磁性能。结果表明，磁性能受稀土金属钕和结构性能的影响。由于钕和钴的协同效应，Nd/Co/PA66纳米电缆的剩余磁化率最大。此外，还详细讨论了纳米结构的磁化过程。我们认为，这些方法可能为铁磁合金和永磁材料提供思路，并适用于未来在垂直记录介质中的应用。
