在高压下合成了不同氧化学计量比的BiMnO（3-delta）组合物。斜方晶系BiMnO（2.99）和单斜晶系BiMnO（2.84）分别表现出倾斜的反铁磁性和铁磁性。BiMnO（2.94）和BiMnO（2.89）也是单斜晶系，并显示出铁磁性，但它们似乎可能包含不止一个相的畴。
BiMnO(3-delta) compositions differing in oxygen stoichiometry have been synthesized under high pressure. Orthorhombic BiMnO(2.99) and monoclinic BiMnO(2.84) exhibit canted antiferromagnetism and ferromagnetism respectively. BiMnO(2.94) and BiMnO(2.89) are also monoclinic and show ferromagnetism, but it seems possible that they may contain domains of more than one phase.
