Abstract: Ni0.5Zn0.5Fe2O4 micro-particles with average particle size 283 nm were synthesized via solid state synthesis route. The structural and surface morphological analysis were carried out utilizing X-ray diffraction (XRD) and Field Emission Scanning Electron Microscope (FESEM) respectively. The X-ray and FEASEM analysis reveals its pure phase formation, cubic spinel structure with space Fd3 m [O7h] and inhomogeneous grain growth in micrometer range of as-prepared samples. The average particles size was estimated from histogram of several particle sizes. The average particles size was estimated from histogram of several particle sizes. The grain, grain boundary contribution is prominent from RT to 200 degrees C and electrode ceramic interface effect incorporated above 300 degrees C which are ascertained from Nyquise (Z’ vs. Z”) plot of impedance. The dielectrics constant and loss are decreased with dispersion of high frequency and enhances with high temperature.
