Abstract
In this study, Ni0.7 Zn0.3 Fe2O4 was prepared by chemical deposition at temperatures of 700°C, 800°C, 900°C, 1000°C, 1100°C and 1200°C respectively, The various applications on the spectral and structural analysis of Ni0.7 Zn0.3 Fe2O4 compounds, as observed by X-ray diffraction technique, show that all samples with spherical structure and interstitial intervals have the same Miller coefficients (2.958, 2.517, 2.422, 2.093, 1.717, 1.613, 1.481 and 1.279) nm. Spectral impedance is a tool for understanding the various contributions to electrical properties of semiconductors. Through complex, intricate and complex permutations, the contributions of grains and boundary grains were understood in the electrical characteristics of the samples. The spectral analysis of the impedance as a frequency function (1 kHz-5 MHz) was done for Ni0.7 Zn0.3 Fe2O4 samples. it showed the imaginary part of the reluctance as a function of the complex impedance that shows Debye type of relation time. Cole-Cole plots (relation between real and imaginary parts for impedance complex) showed a non-Debye type of relaxation time of insulation.
