摘要：

Lead-free multiferroic ceramics of 0.75Bi(1-x)Er(x)FeO(3)-0.25BaTiO(3) + 1 mol% MnO2 were synthesized by a conventional ceramic technique, and their structure, piezoelectric, ferroelectric and ferromagnetic properties were investigated. All the ceramics possess a perovskite structure. The crystal structure of the ceramics is transformed from rhombohedral to orthorhombic phase with increasing x. The ceramics with x = 0.125-0.15 exhibit good electric insulation (R = 2.75-2.83 x 10(10) Omega cm) and strong ferroelectricity (P-r = 13.4-14.2 mu C cm(-2)). The remanent magnetism M-r and saturated magnetization M-s of the ceramics are greatly improved by 380 and 722 % with increasing x from 0 to 0.15, respectively. The present materials exhibit strong ferroelectricity, considerable improved ferromagnetism and relatively good piezoelectricity, suggesting potential applications in advanced multiferroic devices.
