利用中子粉末衍射、电子衍射和二次谐波产生等方法，我们发现BiScO_3的结构与多铁性BiMnO_3的结构密切相关，但BiScO_3的晶体属于中心对称空间群C_2/c。这些结果提出了一个问题的起源BiMnO 3的铁电性。BiScO 3可以作为一个模型系统，以了解Mn 3+离子在BiMnO 3的铁电性的作用。
With neutron powder diffraction, electron diffraction, and second-harmonic generation, we have shown that BiScO3has a structure closely related to that of multiferroic BiMnO3, but BiScO3crystallizes in the centrosymmetric space group ofC2/c. These results bring up a question about the origin of ferroelectricity in BiMnO3. BiScO3may serve as a model system to understand the role of Mn3+ions in the ferroelectricity of BiMnO3.
