Abstract
Nanowires made of FexCoyCu \(_{{(100-x-y)}}\) and FexNiyCu \(_{{(100-x-y)}}\) alloys have been investigated. Specific features of the formation of these structures by template synthesis are studied. Elemental analysis of the nanowires grown at successively increasing voltages revealed a significant decrease in the amount of copper, as well as a change in the ratio of the main magnetic elements. X-ray diffraction analysis showed that FeCoCu is a three-component solid solution, whereas FeNiCu contains three phases of solid solutions: FeCu with a Cu content up to 80%, FeNi with a high iron content, and NiCu in the amorphous or fine-grained state with a Ni content up to 80%. Mössbauer spectroscopy revealed that addition of copper may cause a change in the misorientation angle of magnetic moments in nanowires; this finding correlates with the magnetometry data.
