摘要：

(Figure Presented) Multiferroic material: RbI 0.82MnII0.20-MnIII 0.80[FeII(CN)6]0.80[Fe III(CN)6]0.14·H2O (see picture; MnII red octahedra, FeIII red spheres, Mn III blue octahedra, FeII blue spheres, CN white lines, gaps are Fe vacancies; H2O omitted) displays both ferroelectricity, explained by a mixing of FeII, FeIII, Fe vacancies, MnII, and Jahn-Teller-distorted MnIII centers, and ferromagnetism, caused by a parallel ordering of the magnetic spins of Mn III. © 2007 Wiley-VCH Verlag GmbH & Co.
