| Abstract: | Polycrystalline Bi0.6Ca0.4Mn0.2Fe0.8O3 was prepared by sol-gel method.The microstructure and electrical properties of sample were investigated.The research shows that the electrical constant reduce gradually with the increment of the frequency and the electrical constant increase with the increment of the temperature.We discover that electrical properties of Bi0.6Ca0.4MnO3 is improved obviously by doping Fe to the Mn of the Bi0.6 Ca0.4 MnO3. |
