摘要：

Dense Bi0.87La0.05Tb0.08FeO3 ceramics were prepared by spark plasma sintering. The sample showed stable dielectric constant and low dielectric loss (similar to 5%), and a saturation ferroelectric loop with remnant polarization of 17 mu C/cm(2) and saturation polarization of 19 mu C/cm(2), as well as good ferromagnetism with saturation magnetization of 0.71 emu/g, at room temperature. After the sample was poled, its piezoelectric constant was measured as 12.8 pC/N, and, in particular, an obvious magnetoelectric coupling was observed. (C) 2007 American Institute of Physics.
