Zinc ferrite magnetic nanoparticles (ZnFe2O4) have been successfully encapsulated with various concentration of PEG-4000. ZnFe2O4 powder synthesized by co-precipitation method. X-ray Diffraction (XRD) analysis showed the decrease of nanoparticles size, from 8.5 to 6.6 nm. This result also confirmed by TEM analysis which showed the decrease of nanoparticles size from 8 to 6 nm. XRD result also showed ??Fe2O3 phase ratio was decreased, which is antiferromagnetic. The Result of Fourier Transform Infra-Red spectroscopy analysis showed the peak shift of C-O at 1110.98 cm-1 which is the structure bond of PEG the peak shift of Fe-O tetrahedral site at 370.63 cm-1 which is a uniform pattern of Zinc Ferrite.
