ABSTRACT

 

The powders of nano crystalline Ni 0.6 Zn0.4 (Fe2O4) was synthesized by using chemical co- precipitation method and followed by annealing temperature at 100°C, 600°C and 900°C. X-ray powder diffractometry (XRD), Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR) were carried out to investigate structural and chemical aspects of Ni0.6-Zn0.4 ferrite. The cubic spinal structure in single phase has been confirmed by X ray diffraction. The average crystallite size was calculated from the line broadening in XRD pattern also observed that the size of the particles was increased with sintering temperature. The surface morphology of the samples was studied using Scanning Electron Microscopy (SEM) technique. The IR Spectra for the samples measured in the range of 4000-400 cm-1 exhibit symmetric stretching mode of vibration of tetrahedral and octahedral sites at 669.7 cm-1 and 545.6 cm-1. The dielectric property of the Ni 0.6 Zn0.4 (Fe2O4) was also studied for different temperatures.
