Multiferroic Bi 0.95 −x La 0.05 Tb x FeO 3 (BLTFO) ceramics were prepared by spark plasma sintering. The protection of CeO 2 powders in the spark plasma sintering process can effectively restrain the valence fluctuation of iron ions and high‐dense BLTFO ceramics with good dielectric and ferroelectric properties are fabricated. The BLTFO ceramics have low loss (tanδ∼5%) between 10 2 and 10 6 Hz. The doping of Tb can increase the dielectric and ferromagnetic properties, but decrease the ferroelectricity of BLTFO ceramics.
