Facile synthesis of high magnetization long term stable bimetallic FeCo nanoparticles
Authors
Abstract
In this study, we reported a facile synthesis of bimetallic FeCo nanoparticles (Fe-Co NPs) by FeSO4.7H2O and Co(Ac)2.4H2O in the presence of sodium borohydride and 2-thiotic acid. The structure and morphology of the nanoparticles were characterized by X-Ray Diffraction (XRD), Energy-dispersive X-ray spectroscopy (EDS), and Transmission Electron Microscopy (TEM). These small, spherical shape and pure phase FeCo bimetallic nanoparticles have saturation magnetization up to 221 emu/g. The results suggest that the long term stable and high saturation magnetization (Ms) FeCo nanoparticles can be used for data storage, catalysis, environmental remediation, high-performance inductors, magnetic hyperthermia treatment and magnetic resonance imaging applications.
