ABSTRACT

This article illustrated the impact of synthesized micro-structured spinel-type polycrystalline ferrites. The technique of conventional double sintering is used 〖MgFe〗_2 0_4, 〖Mg〗_0.5 〖Zn〗_0.5 〖Fe〗_2 O_4,〖Mg〗_0.35 〖Cu〗_0.20 〖Zn〗_0.45 〖Fe〗_2 O_4 and 〖Mg〗_0.35 〖Cu〗_0.20 〖Zn〗_0.45 〖Mn〗_0.06 〖Fe〗_1.94 O_4 to investigate their impact on the size of the grain, magnetic properties and the effect of divalent substitutions. Impurity phases aren’t detectable in the taken cubic spinel of single phases in the X-ray diffraction patterns. In the sample investigation it was observed that the density was tensed to increase, while the porosity decreased with the replacement of divalent ions. Microstructures show that there is an increase in grain growth as the addition of CuO is attributed to the liquid process due to CuO during sintering. At room temperature, all the samples exhibit a nice homogeneity for the sharp deterioration of  in T. Lower coercivity is found in all samples suggesting that the compounds are a type of soft ferrite magnets.
