Abstract: 
In this work, Mn0. 5Zn0. 5Fe2O4 ferrite powders were prepared through glycine-nitrate combustion method at different molar ratios of glycine to nitrate. X-ray diffraction patterns showed that samples crystallized successfully in a spinel-type structure in all reactions. Magnetic properties were measured using a vibrating sample magnetometer. The saturation magnetization values of the as-synthesized samples were found to be in the range of 59. 5-63. 3 emu/g. Dielectric and electromagnetic properties were examined by a LCR meter. The sample synthesized at the lowest G/N ratio showed the lowest magnetic loss and the highest permeability. The complex impedance analysis illustrated only one semicircle indicating the predominant effect of grain boundary property of the material.
