Abstract

Nanowires of FexCoyCu(100–x–y) and FexNiyCu(100–x–y) alloys have been studied. The features of obtaining such structures by the matrix synthesis method have been investigated. Elemental analysis of nanowires grown at sequentially 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 phase analysis showed that FeCoCu is a three-component solid solution, while FeNiCu contains three phases of solid solutions: FeCu with copper content up to 80%, FeNi with high iron content, and NiCu in an amorphous or fine-crystalline state with nickel content up to 80%. Mössbauer spectroscopy revealed that the addition of copper can lead to a change in the angle of magnetic moment misalignment in nanowires, which correlates with magnetometry data.
