0.7Bi (Fe 1− x Cr x ) O 3 –0.3BaTiO 3 ( x =0, 0.05, 0.1, 0.15, 0.2) solid solutions were prepared by the traditional ceramic process. X‐ray diffraction revealed that all samples with x =0–0.15 showed pure rhombohedral perovskite structure. Frequency dependences of dielectric constants and dielectric loss were investigated. Proper amount of Cr could decrease the dielectric loss. Measurements of magnetic and ferroelectric hysteresis loops at room temperature indicated that the solid solutions showed ferroelectricity and ferromagnetism simultaneously. Magnetization of the solid solutions was with increasing content of Cr.
