facile synthesis of high magnetization long term stablebimetallic feco nanoparticles

In this study, we reported a facile synthesis of bimetallic feco nanoparticles (fe-co nps) by feso4.7h2oand co(ac)2.4h2o in the presence of sodium borohydride and 2-thiotic acid. the structure and morphologyof 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 fecobimetallic nanoparticles have saturation magnetization up to 221 emu/g. the results suggest that the longterm stable and high saturation magnetization (ms) feco nanoparticles can be used for data storage,catalysis, environmental remediation, high-performance inductors, magnetic hyperthermia treatment andmagnetic resonance imaging applications.
