Abstract

Nanowires (NWs) with alternating layers of magnetic and nonmagnetic metals (Ni/Cu, Co/Cu) in track membranes with pores of small diameters (100, 65, and 30 nm) have been obtained by template synthesis. The problem of reducing the thickness of separate layers has been solved. The processes of electrodeposition at a successive decrease in the transmitted charge are investigated. The topography of the obtained structures; the diameters of NWs; and the thickness of separate layers, especially the interfaces between layers, are studied by scanning electron microscopy and transmission electron microscopy with elemental analysis. The potential of the techniques, which previously proved to be efficient in the formation of alternating layers in matrices with pores of large diameters, is estimated.

具有薄层的 Ni/Cu 和 Co/Cu 纳米线的基质合成与结构
摘要 通过模板合成法获得了在具有小直径(100、65 和 30 nm)孔隙的轨道膜中具有磁性和非磁性金属(Ni/Cu、Co/Cu)交替层的纳米线(NWs)。减小独立层厚度的问题已经解决。研究了透射电荷连续减少时的电沉积过程。通过扫描电子显微镜和带有元素分析的透射电子显微镜,研究了所获得结构的形貌、NW 的直径、独立层的厚度,特别是层与层之间的界面。这些技术以前曾被证明能有效地在具有大直径孔隙的基质中形成交替层,现对这些技术的潜力进行了估计。
