Ordered arrays of ferromagnetic nanowires with (Fe, Co)-Pd compositions have been fabricated from chloride based electrochemical baths by means of template-assisted electrodeposition into self-assembled nanopores of anodic alumina membranes. The nanowires have a diameter and inter-spacing distance of 72 nm and 105 nm, respectively, and around 0.6-1.6 microm in length. Their microstructure and basic magnetic properties are reported. Coercivity, remanence and respective angular dependences on the applied field up to +/- 3 T have been determined from room temperature hysteresis loops measured in a VSM. The study has been performed paying particular attention to the influence of increasing from about 27 up to 63 percent the Pd content in the nanowire alloy.
通过模板辅助电沉积法，将基于氯化物的电化学浴液中的（铁、钴）-钯成分制成有序排列的铁磁纳米线，沉积到阳极氧化铝膜的自组装纳米孔中。纳米线的直径和间距分别为72纳米和105纳米，长度约为0.6 - 1.6微米。报告了它们的微观结构和基本磁性能。通过在振动样品磁强计（VSM）中测量的室温磁滞回线，确定了矫顽力、剩磁以及在高达±3特斯拉的外加磁场下各自的角度依赖性。该研究特别关注了纳米线合金中钯含量从约27%增加到63%的影响。
