The magnetic properties of MgR1-xRZnRxRFeR2ROR4R (where x = 0.3,0.4,0.5,0.6) ferrites have been studied. Magnesium Zinc Ferrites was synthesized by oxalate co-precipitation method at different synthesis temperature. Magnetization parameters such as saturation magnetization were calculated and the results are discussed. Saturation magnetization was found to be in the range 2 emu/gm to 8.28 emu/gm when the samples were synthesized below 100P0PC. The SEM micrographs showed the uniform distribution of the particles. The SEM micrographs indicated the distribution of grains and showed the variation of the grain size of the samples with composition and temperature.The saturation magnetization had greater value when grain size had lower value. for lower temperature of synthesis, the grain size was more.
