摘　　要：以多孔氧化铝为模板,采用控电位沉积方法制备了Ni-Fe纳米线及其阵列。能谱分析表明,纳米线组成为Ni79-Fe21。X-射线衍射测试表明,Ni-Fe纳米线呈面心立方Ni固溶体结构。磁滞回线测试表明,控电位制备的Ni-Fe纳米线阵列具有良好的软磁性能,500℃退火处理后,Ni-Fe合金纳米线具有硬磁性。Ni-Fe alloy nanowires were successfully prepared by the combination of electrodeposition method and anodic aluminum oxide （AAO） templating method.Results of energy dispersive X-ray spectroscopy（EDS） showed that the composition of nanowires was Ni79-Fe21.X-ray diffraction（XRD） indicated that the Ni-Fe nanowires showed a face-centered-cubic （fcc） structure of Ni solid solution.Hysteresis loops showed that the Ni-Fe alloy nanowire arrays had good soft magnetic properties.After annealing at 500℃,the Ni-Fe alloy nanowire arrays changed to have hard magnetic properties.
