Bi3Mn3O11: a new KSbO3-type random ferrimagnet with high T(C).
A new compound, Bi(3)Mn(3)O(11), with a KSbO(3)-type structure was prepared using a high-pressure technique. Its structural, chemical, and magnetic properties have been investigated. Bi(3)Mn(3)O(11) was shown to be a ferrimagnet with rather high T(C) despite the random distribution of manganese ions with different oxidation states in one site. Bi(3)Mn(3)O(11) gradually loses oxygen on heating forming several phases with the same structure but with different magnetic properties. These findings may revive interest in the KSbO(3) family of compounds, which is rather adaptive considering the cation variations and oxygen content.
