The increasing addition of Tb in the system Bi1−xTbxFeO3 produces a progressive modification of the crystal structure from rhombohedral R3c to orthorhombic Pnma which results in the appearance and enhancement of the net magnetization, with the composition x ≈ 0.15–0.20 being a promising candidate for magnetoelectric applications.
