Preparation and Characteristics of BiFeO3 Ceramics Doped by MnO2 and Co2O3

摘要

BiFeO3-based single-phase multiferroics have been widely studied in both ceramics and films.However,the macroscopic magnetic properties of BiFeO3 ceramics were now most very weak.In this work,MnO2 and Co2O3 were used as B-site substitutes in BiFeO3 ceramics in order to the enhancement of magnetic properties.The change of magnetization was analyzed based on the phase composition and the microstructure of ceramics.
