Local structure analysis of BiFeO-BaTiO solid solution

Yoneda, Yasuhiro   ; Kim, S.*; Wada, Satoshi*

In a solid solution formed with BiFeO and BaTiO, a pseudo cubic phase appears at room temperature with a BaTiO composition of 0.3 to 0.7. Since the ferroelectricity is not lost even in the Cubic structure, a structural analysis using pair distribution function was performed to clarify the origin of the ferroelectricity. The local structure of these solid solutions was consistent with the pure limits of BiFeO and BaTiO, respectively, but when the BaTiO composition was 0.3, a structure peculiar to the solid solution appeared.
