Abstract

Nanopowders of the binary system of immiscible components Fe and Cu are synthesized by gas condensation of metal vapors. The structure and magnetic properties of nanopowders of various compositions are investigated, and their Mössbauer spectra are analyzed. It is shown that the method allows one to obtain nonequilibrium Fe(Cu) and Cu(Fe) solid solutions, in which the concentration of dissolved elements depends on the synthesis conditions.

气体冷凝法合成Fe-Cu系统纳米粉及其结构与磁性

摘要

不溶性成分Fe和Cu的二元体系的纳米粉是通过金属蒸气的气体冷凝而合成的。研究了各种组成的纳米粉的结构和磁性，并分析了它们的Mössbauer光谱。结果表明，该方法可以得到非平衡的Fe（Cu）和Cu（Fe）固溶体，其中溶解元素的浓度取决于合成条件。
