A Composite of (95%) La2CoMnO6+ (5%) Ba0.5Na0.5TiO3 : Study of Structural and Dielectric Properties

Abstract

This project work reports synthesis, structural and dielectric nature of composite of the type (95%) La2CoMnO6+ (5%) Ba0.5Na0.5TiO3. The composite was characterized at room temperature for structural and dielectric properties. The structural characterization X-ray diffraction was carried for structural confirmation. The XRD data study convey the sample is dual phase in nature evident from the corresponding diffraction peaks. Monoclinic phase was acquired by La2CoMnO6 and the space groupof the phase is P 1 21/n whereas Ba0.5Na0.5TiO3 phase has acquired cubic structure with space group Pm-3m. The frequency dependent dielectric constant examined reveals high dielectric constant which decreases with increase in applied ac field values. Dielectric loss calculated shows the behaviour like dielectric constant which initially decreases abruptly with applied field and later attains frequency independent values. However, the ac conductivity was observed higher in the as synthesized.
