【 摘 要 】

Nanoparticles nickel ferrite of size 6 - 8 nm, synthesized by the coprecipitation method with x varying from 0 to 1.0. The powder samples were characterized by XRD, VSM and FTIR. The average crystallite sizes of the particles were determined from X-ray diffraction. X-ray analysis showed that the samples were cubic spinel. The lattice constant (a o) increased with the increase in zinc substitution. The specific saturation magnetization (M S) of the particles was measured at room temperature. The magnetic parameter of M S, was found to decrease with the increase in zinc substitution. Fourier transform infrared spectroscopy (FTIR) spectra of the Ni1-xZn xFe2O4 with x = 0, 0.5, 1 in the range 400 - 4000 cm-1 were reported. The spinel structure and the crystalline water adsorption of Ni1-xZn xFe2O4 nanoparticles were studied by using FTIR.
