Phase Transitions of BiFeO₃-LaFeO₃Solid Solutions

Abstract

Bi0.95La0.05FeO3 were synthesized by the solid-state reaction. Bi0.95La0.05FeO3 showed variety of crystallinity depending on the synthesized condition. The average and local structures of the Bi0.95La0.05FeO3 crystals were analyzed by Rietveld refinement and pair-distribution function method, respectively. Although the average structure does not depend on the synthesized condition, the mosaic block size of the Bi0.95La0.05FeO3 crystals were changed by the synthesized condition. The difference of the mosaic block size is a cause of the different thermal properties.
