A detailed study of structural, electric and magnetic properties of FeCo-alloyed nanotubes (NTs) having a different iron to cobalt ratio with an outer diameter of 110 nm and a length/diameter aspect ratio of more than 100 was carried out. The nanotubes were produced by electrochemical deposition of metal in the pores of PET film template. Ion-track technology was used to produce templates with cylindrical pores. An increase in the deposition potential from U = 1.5 V to $U=2$.0 V led to a shift in the atomic ratio of metals in the FeCo alloy from 42 to 51 at.% in favour of cobalt as confirmed by energy dispersive analysis. Analysis of structural features by X-ray diffraction and the selected area electron diffraction revealed that at higher deposition potentials the degree of crystallinity of FeCo NTs increases from a nearly random orientation of crystallites at $U=1.5$ V to a textured polycrystal at $U=2.0$ V. This was also consistent with a corresponding increase in electrical conductivity. Based on the analysis of hysteresis curves and Mössbauer spectra, the dominant directions of the texture with respect of the NTs axis were established. An axial magnetic anisotropy and rather high magnetic coercivity ($\mathrm{\sim }$ 500 Oe for the orientation with the DC magnetic field parallel to tube axes) were observed and attributed to a dominant contribution of the shape anisotropy with a minor crystal anisotropy term due to the textured growth of the nanotubes. It was shown that the technology of electrochemical deposition in the ion-track template pores makes it possible to synthesize the nanotubes and nanowires with the structural and magnetic properties, which have a high interest with the point of view of a fundamental physics and their technological applications.

进行了铁钴比不同，外径为110 nm，长径比大于100的FeCo合金纳米管（NTs）的结构，电学和磁学性能的详细研究。通过将金属电化学沉积在PET薄膜模板的孔中来生产纳米管。离子跟踪技术用于生产具有圆柱孔的模板。沉积电位从U = 1.5 V增加到$ü=\mathrm{2个}$0.0 V导致FeCo合金中金属的原子比从42 at。％迁移到51 at。％，有利于钴，这一点已通过能量色散分析得到了证实。通过X射线衍射和选定区域电子衍射对结构特征的分析表明，在较高的沉积电势下，FeCo NTs的结晶度从晶粒的几乎随机取向开始增加。$ü=\mathrm{1个}。5$ V到一个有纹理的多晶 $ü=\mathrm{2个}。0$V.这也与电导率的相应增加相一致。通过对磁滞曲线和Mössbauer光谱的分析，确定了纹理相对于NTs轴的主导方向。轴向磁各向异性和相当高的磁矫顽力（$\mathrm{〜}$观察到500 Oe的直流磁场平行于管轴的取向），这归因于由于纳米管的织构生长，形状各向异性具有较小的晶体各向异性项的主要贡献。结果表明，在离子轨迹模板孔中进行电化学沉积的技术使合成具有结构和磁性性质的纳米管和纳米线成为可能，这对基础物理学及其技术应用具有很高的兴趣。 。
