A study of structure, microstructure and dielectric property of composite of la doped BiFeO3 and BaTiO3
In this article, we studied theBi0.9La0.1FeO3 (BLFO) and BaTiO3 (BTO) and their composite (0.85) Bi0.9La0.1FeO3-(0.15) BaTiO3 for their structural and dielectric properties. The samples were prepared via conventional solid state reaction route. The X-ray diffraction spectroscopy analysis reveals the rhombohedral crystal structure for BLFO and Cubic structure for BTO. While, Bi0.9La0.1FeO3-(0.15) BaTiO3 depicts the presence of both the phases. The compositional and morphological studyof the composite was also carried out. The frequency dependent dielectric analysis shows that the samples exhibit a good dielectric property with low loss in directric values. The ac conductivity at lower frequency shows independent of the field but after the threshold value of frequency, the conductivity increases due to hopping of charge carriers. It is concluded that the samples are promising candidates for good energy storage capability, required in storage device applications.
