Abstract
Dense Bi0.87La0.05Tb0.08FeO3 ceramics were prepared by spark plasma sintering. The sample showed stable dielectric constant and low dielectric loss (∼5%), and a saturation ferroelectric loop with remnant polarization of 17μC∕cm2 and saturation polarization of 19μC∕cm2, as well as good ferromagnetism with saturation magnetization of 0.71emu∕g, at room temperature. After the sample was poled, its piezoelectric constant was measured as 12.8pC∕N, and, in particular, an obvious magnetoelectric coupling was observed.
