Summary: The manganese-substituted nickel-rich lithium-cobalt oxide Li2Ni6MnxCo2-xO10 was successfully synthesized using the sol-gel autocombustion method. The structure and morphology of the material were characterized by XRD and SEM techniques, respectively. The prepared nanomaterial exhibited a hexagonal structure with a secondary phase. The average crystallite size was determined to be between 12 and 27 nm using different methods. SEM analysis showed the surface morphology and particle size distribution. The dielectric characteristics of the material were frequency-dependent, indicating suitability for high-frequency devices. Magnetic measurements revealed variations in saturation magnetization and coercivity with increasing Mn concentration. The obtained dielectric properties suggest potential applications in energy storage.

Summary: The perovskite-type phase CaCu3Ti4O12 has promising dielectric properties, but the phenomenon of giant permittivity in this material has not been fully explained. In this study, Europium with similar electronegativity and ionic radius as Calcium was tested as a partial or complete substitute. A series of materials, including CaCu3Ti4O12, Eu0.4Ca0.6Cu3Ti4O12, and EuCu3Ti4O12, were prepared using a sol-gel method and sintering. The influence of microstructure and phase composition on the dielectric properties of the samples, as well as the effect of sintering temperature, was investigated. Secondary phases and microstructure were found to play a significant role in improving the permittivity values, which were found to be giant at higher frequencies but significantly different for specific compositions.
