文摘

Simple Bi-based compounds, BiMO₃, are quite interesting materials. They offer large variations in crystal symmetries, polarity, and properties. Their chemical simplicity makes them ideal systems for materials fabrications, theoretical understanding, and thin-film growths. They can only be prepared at high-pressure high-temperature conditions (except for BiFeO₃) in a bulk form. Some of them can be stabilized in thin films (M=Al, Sc, Cr, Mn, and Fe). In this review, we collect and analyze the recent experimental and theoretical results on BiMO₃ with M=Al, Sc, Ti, V, Cr, Mn, Co, Ni, Cu, Ga, In, and Rh. In addition, unresolved problems and desirable future experiments are emphasized especially for the highly controversial compound BiMnO₃.
