Muitiferroic ceramics Bi_0.8Ba_0.2Fe_0.9M_0.1O₃(M = Cr、Mn and Ti) were prepared by using conventional solid state reaction method. The pure phase with rhombohedral perovskite structure (space group R3c) was confimd by the X-ray diffraction measurements for all samples. The maximum value of the remnant polarization (2Pr) and the minimum value of the dielectric constant at room temperature and low frequencyare for Bi_0.8Ba_0.2Fe_0.9Ti_0.1O₃samples are 0.64 μC/cm₂ and 140, respectively. The dielelctric constant and dielelctric loss decrease with increasing frequency and then become nearly constant at higher frequency for all samples. The maximum value of the remnant magnetization (2Mr) for Bi_0.8Ba_0.2Fe_0.9Mn_0.1O₃samples at room temperature is 1.46emu/g by the M-H loops measurements. A remarkable change in the P-E loops were observed whether a bias dc magnetic field was applied or not, approving the existence of the magnetoelectric coupling indirectly therein in multiferroic ceramics Bi_0.8Ba_0.2Fe_0.9M_0.1O₃(M = Cr、Mn and Ti). And the maximum value of magnetoleectric coupling for Bi_0.8Ba_0.2Fe_0.9Cr_0.1O₃samples is 5.8 mJ/cm₃.
