ABSTRACT Spinel ferrites are magnetic materials that have exceptional structural features. In this study we investigated the influence of Gallium Doping on the structural, magnetic and electrical properties of Ga x CoFe 2-x O 4 (x = 0.000, 0.050, and 0.100). As prepared material is sintered at 600 °C for 4 h in muffle furnace with a heating rate of 100 °C/h. As prepared ferrite powder were characterized by X-Ray Diffraction (XRD), FTIR spectroscopy, and Scanning Electron Microscopy – Energy Dispersive X-ray spectroscopy (SEM – EDX). The results reveals that the formation of pure cobalt ferrite phase for low gallium content. The study of DC electrical resistivity of the prepared sample Ga x CoFe 2-x O 4 were carried out in the temperature range of 300-800K using standard two probe method. For Magnetic analysis as prepared samples were tested with Vibrating Sample Magnetometer (VSM). Measurements were considered for all samples.
