Preparation and Ferroelectromagnetic Characteristics of Bi2SrNdNb2FeO12 Ceramic
The solid solutions of NdFeO3-Bi2SrNb2O9 (1:1ratio) of the Aurivillius-type compounds was prepared by solid-state reaction. The room structural data were obtained from X-ray diffraction (XRD) and confirmed a Three-layered Aurivillius phase. The dielectric measurement showed no anomalies due to the high conductivity of these samples at elevated temperature. From the magnetic measurement the compounds were found to be of canted antiferromagnetic at room temperature. It is revealed that the formation of Fe2+ can be suppressed by the pre-oxidation of Fe2O3，This result may have implications for further studies on leakage current control of these materials. In all, we’ve synthesized a new material that is ferroelectromagnetic in nature.
