| Abstract: | MnxNi0.5−xZn0.5Fe2O4, (x=0.05, 0.1, 0.2, 0.3, 0.4) ferrites synthesized by the citrate precursor method are investigated in the present work. Compositional variation of AC resistivity is studied and values up to 103 times greater than those for samples prepared by the conventional ceramic method are observed. It is found that resistivity decreases with increase in Mn concentration except for x=0.3, where it shows a rise. Frequency variations of both dielectric constant and relative loss factor (rlf) are reported in the present work. It is observed that dispersion in dielectric constant is greatly influenced by the Mn concentration. Possible mechanisms contributing to these properties are discussed. Hysteresis properties are also reported. |
