Abstract

Nanocrystalline mixed spinel ferrite of Zn0.5Ni0.5Fe2O4 magnetic nanoparticles (MNPs) has been successfully synthesized by coprecipitation method and encapsulated and PEG-4000 with various concentrations. X-Ray Diffraction (XRD) patterns showed that nanoparticles contained Zn0.5Ni0.5Fe2O4 spinel ferrite with the particles size of 15.2 nm. After PEG-4000 encapsulation, particles size decrease became 13.3 nm. Transmission Electron Microscopy (TEM) image showed that the nanoparticles still aglomerate after PEG-4000 encapsulation. The coercivity (Hc ) of Zn0.5Ni0.5Fe2O4 was 50.7 Oe. The Hc decrease after PEG-4000 encapsulation became 47.9 Oe, respectively. It is due to the decrease of particle size. The saturation magnetization (Ms ) of Zn0.5Ni0.5Fe2O4 was 18.4 emu/g, and decrease to 17.1 emu/g after PEG-4000 encapsulation. This is because PEG-4000 has paramagnetic properties.
