We have fabricated extremely uniform arrays of polycrystalline Fe-Co-Ni ternary alloy nanowires having composition Fe 12.3 wt.%, Co 43.9 wt.% and Ni 43.8 wt.%. The wires are made by electrodeposition into nanoporous alumina templates, using an electrodeposition voltage of 15 V at 1000 Hz. Nanowires have been fabricated having diameters ranging from 43 nm to 120 nm, and lengths of 3 microm to 7 microm, as dependent upon template topology. The magnetization easy axis lies along the nanowire length, with an easy axis coercivity of 72 kA/m.
我们制备了成分分别为铁12.3 wt.%、钴43.9 wt.%和镍43.8 wt.%的多晶铁-钴-镍三元合金纳米线的极其均匀的阵列。这些纳米线是通过电沉积到纳米多孔氧化铝模板中制成的，在1000 Hz频率下使用15 V的电沉积电压。根据模板拓扑结构，制备出了直径范围为43纳米至120纳米、长度为3微米至7微米的纳米线。易磁化轴沿纳米线长度方向，易轴矫顽力为72 kA/m。
