Abstract

In this study, we reported a new BaTiO₃–Na_0.5Bi_0.5TiO₃–Nb₂O₅–Mn₂O₃/Fe₂O₃/Co₃O₄/In₂O₃X8R system with high dielectric constant (>2100) at room temperature. The impacts of oxygen vacancy ((Formula presented.)) on dielectric, electrical conductivity, and ferroelectric properties were systematically studied. The Curie point is largely depended on the (Formula presented.) concentration, which can be confirmed by the dielectric behavior and A_1goctahedral breathing modes in Raman spectrum. In addition, the activation energy of (Formula presented.) diffusion is greatly reduced with the increase in (Formula presented.) concentration. It was found that the remnant polarization and coercive field were both decreased with increasing (Formula presented.) concentration, due to the facilitated defect dipoles reorientation and domain switching. © 2016 The American Ceramic Society
