Synthesis and Characterization of Magnetite Nanoparticles and the Effect of [Fe(sac)2(H2O)4].2H2O complex on its magnetic properties

A novel inorganic complex (shell)@metal oxide (core) was demonstrated by simple and highly efficient synthesis of fe3o4 nanoparticles (fe3o4nps) coated by [fe(sac)2(h2o)4] .2h2o complex through one-pot reaction of prepared fe3o4 nanoparticles and [fe(sac)2(h2o)4].2h2o. the fe3o4 nps structure was characterized by infrared spectroscopy (ir), scanning electron microscope (sem) and energy dispersive x-rays (edx) while the resulted [fe(sac)4(h2o)2]@fe3o4nps was characterized using ir spectroscopy and xrd. the magnetic feature, which is one of physical properties of fe3o4nps and the newly synthesized core-shell [fe(sac)2(h2o)4]@fe3o4nps were examined in order to study how the fe in its complex effects on the magnetic properties of magnetite nanoparticles.
