使用含有直径为（500 +/-50）nm的圆柱形蚀刻轨道纳米通道的（30 +/-1）μ m厚的聚碳酸酯模板进行Ni纳米线的电沉积。使用10（4）个通道/cm（2），通过在-0.1 V和-1.5 V之间的范围内改变相对于Ag/AgCl参比电极的沉积电位，在恒电位模式下确定-1.0 V的最有利沉积电位。所得到的单线具有约200 W的电阻，并显示出1%的各向异性磁阻（AMR）效应，适用于方向敏感的磁场传感器。
Polycarbonate templates of ( 30 +/- 1) mu m thickness containing cylindrical etched-track nanochannels of ( 500 +/- 50) nm diameter were used for electrodeposition of Ni nanowires. Using 10(4) channels per cm(2), the most favourable deposition potential of -1.0 V was determined in a potentiostatic mode by varying the deposition potential with respect to an Ag/AgCl reference electrode over a range between -0.1 V and -1.5 V. The deposition efficiency at -1.0 V was estimated around 10%. The resulting single wires had a resistance around 200 W and showed an anisotropic magnetoresistance (AMR) effect of 1%, applicable to directionally sensitive magnetic field sensors.
