• The compositional and thermal evolution of the crystal structure of the solid solution Bi_1-xSm_xFeO₃ synthesized at a high pressure of 4 GPa was investigated. It was found that Bi_1-xSm_xFeO₃ with $x = 0.10$ and 0.15 had an antipolar PbZrO₃-type structure with a $\sqrt{2}a\times 2\sqrt{2}a\times 4a$ perovskite superstructure at room temperature, while that with $x = 0.05$ had the same structure as the parent BiFeO₃ ($x = 0$). The $x = 0.10$ sample transforms from an antipolar PbZrO₃-type orthorhombic structure to a polar BiFeO₃-type rhombohedral structure and eventually to a nonpolar GdFeO₃-type structure on heating as Zr-rich PZT.
