中文摘要	Multiferroic ceramics Bi0.9La0.1FeO3 are synthesized by solid-state reactions and sintered at various temperatures. The rhombohedral structure with the space group R3c is confirmed by means of x-ray diffraction, and their multiferroic properties are investigated. Bi0.9La0.1FeO3 ceramics sintered at 880 degrees C are found to have the lowest leakage current density and the largest saturated polarization among all the samples. A diode-like current-voltage hysteresis that could be switched by an external voltage is observed in the Bi0.9La0.1FeO3 ceramics. A typical "butterfly" shaped strain-versus-voltage curve is shown with a maximum strain of 0.09% at 7 kV. Room-temperature magnetization exhibits a hysteresis loop, indicating that the modulation of the spin structure of BiFeO3 has been suppressed.
