Abstract
In this study, Ni0.4Zn0.6Fe2O4 (NZF) and K0.5Na0.5NbO3 (KNN) powders were synthesised using coprecipitation and modified Pechini methods, respectively. X-ray diffraction (XRD) analysis revealed that the powders are composed of only a single phase. The size distribution of aggregated NZF and KNN is bimodal with modes smaller than 0.1 μm and 10 μm in size, respectively. XRD and Rietveld refinement revealed the presence of an orthorhombic (Amm2) structure in KNN, and a cubic (Fd-3m) phase in the NZF material. Scanning electron microscopy showed that the ceramics exhibited cuboid-shaped grain morphologies. Dielectric analysis revealed that the maximum dielectric constant ε is demonstrated by the 90KNN-10NZF composite, reaching ε = 4000 at 100 kHz at the Curie temperature. The electrical characteristics of the material were studied by means of the electrochemical impedance spectroscopy method, which revealed contributions from both grain interiors and grain boundaries. The composite conductivity exhibited a thermally activated behaviour consistent with the Arrhenius model. Analysis of the Nyquist plot indicated a hopping mechanism for charge transport, accompanied by non-Debye type relaxation, as also corroborated by the impedance results. The magnetisation values for KNN are two orders of magnitude lower than those observed for NZF. The correlation between structural, spectroscopic, dielectric, and magnetic properties of NFZ-KNN composites was comprehensively examined.
