摘要：
In this study, nanoparticles were prepared by precipitation from solid solution of saturated binary Cu-Fe alloy with subsequent electrochemical dissolution of the surrounding matrix. As-prepared nanoparticles were studied by the Mossbauer spectroscopy and scanning transmission electron microscopy. Results show that the as-prepared nanoparticles have core-shell character and their mean size is dependent on annealing time. The Mossbauer spectroscopy revealed major crystalline phase which was identified as alpha-Fe and relatively disordered minor phase which was identified as maghemite (gamma-Fe2O3). Magnetic measurements suggest that saturated magnetization is not only dependent on core diameter of nanoparticles but also on its structure.
