摘要

Cation-doped BiFeO_3 ceramics were fabricated by sintering coprecipitated and calcined powders at 700-900℃ to study the effect of cation doping on the leakage current properties of the sintered samples. Among the dopants examined in this study, Ti~(4+), Sn~(4+), or Zr~(4+) doping was found to effectively reduce the leakage current of the samples. In particular, a marked decrease in the leakage current density was achieved at 10% Ti~(4+) doping, which also resulted in the structure change from rhombohedral to cubic. The codoping of Ti~(4+)/Zn~(2+) ions or Ti~(4+)/Ni~(2+) ions brought about a substantial reduction in the leakage current density of the bulk samples by about four or five orders of magnitude at a small doping amount of 2%. This can be explained by the combined effect of Ti~(4+) doping, which basically contributes to the decreased number of oxygen vacancies in the sample, and Zn~(2+) or Ni~(2+) doping, which might assist the homogeneous substitution of Ti~(4+) ions for the Fe~(3+) sites.
