In this paper, nickel nitrate [Ni(NO3)2·6H2O], iron nitrate [Fe(NO3)3·9H2O] nitrate gadolinium [Gd(NO3)3·6H2O], sodium hydroxide (NaOH) as a raw materials, Gadolinium ferrite prepared by hydrother-mal NiGdxFe2?xO4 (x=0, 0.02, 0.04, 0.06, 0.1) nanoparticles and study the effects of re doping on properties of nickel ferrite.Using X-ray diffraction (XRD), X-ray spectroscopy (EDS) to determine the composition, by vibrating sample magnetometer (VSM) and transmission electron microscope (TEM) characterization of morphology. Results indicate that: With the increase in doping by particles of average size becomes smaller, and samples of saturation magnetization and coercivity of particles decreased average size smaller.
