摘　　要：圆柱形坡莫合金纳米线具有单轴形状各向异性以及超高速磁畴壁输运特性,在微磁学研究和超高密度磁存储领域备受关注。因此,研究高质量圆柱形坡莫合金纳米线的制备技术具有十分重要的意义。目前在圆柱形坡莫合金纳米线制备方面,基于模板电沉积法成为了首选方式。由于各种电沉积参数对镍铁合金异常共沉积行为的影响,至今仍无法制备出镍铁成分配比一致以及致密性好的高质量纳米线。本文通过分析基于模板电沉积法的技术难点和原因,总结出可行的解决方案,为高质量坡莫合金纳米线的制备技术提供了参考。Cylindrical permalloy nanowire has attracted much attention in fields of the micromagnetism and the ultra-high density magnetic storage,which owes to the uniaxial shape anisotropy and the ultrafast transport property of the magnetic domain wall.Therefore,the study of the preparation technology of high-quality cylindrical permalloy nanowires has very important significance.At present,the template-based electrodeposition is the preferred method for preparing the cylindrical permalloy nanowires.Due to the effect of various electrodeposition parameters on anomalous codeposition behaviors of the nickel-iron alloy,the template-based electrodeposition has not been able to prepare high-quality permalloy nanowires so far,with the uniform distribution of nickel-iron composition and the good compactness,In this paper,we analyzed technical problems and root causes of the template-based electrodeposition,and summarized a feasible solution to provide a reference for the preparation of high-quality permalloy nanowires.
