Abstract
Di-phase multiferroic composites of xNi.50Zn.40Mn.10Fe2O4.(1-x)Bi0.9La0.1Fe0.98Eu0.02O3 was synthesized with the combination of perovskite and ferrite materials. The compounds are synthesized using the solid-state reaction technique. A union of perovskite and ferrite phases has recognized through the X-ray diffraction (XRD) patterns constitutes the composition. Intense and sharp peaks that we observe in XRD patterns reveal that the phases are well crystalline. The morphology of the prepared samples was studied through Scanning Electron Microscopy, which ensured that the compounds were well-distributed in the form of dense and inhomogeneous grain size distribution. The ac conductivity of composites increases with an increase in frequency, signifying that the conduction occurs due to slight polaron springing, and the conductivity trails the Jonschers’ power law. The contribution of grain and grain boundary in the conduction mechanism is also observed from impedance spectroscopy analysis. Particular semicircular curves starting from the origin are visible in all compositions.
