Chemical modifcation is an efective method for obtaining functional materials with desired properties for technological applications. In this work, the highpressure prepared BiFeO&sub(3) compounds with partial substitution of Bi by Tb ions were studied. The microstructures, phonon modes, and macroscopic magnetic properties of the Bi&sub(1−x)Tb&sub(x)FeO&sub(3) compounds with x = 0.05, 0.1, and 0.3 were investigated. It was demonstrated that the obtained bulk ceramics crystallized in pure rhombohedral (for x = 0.05 and 0.1) or orthorhombic ( x = 0.3) structure with reduced microstrains. The Tb ions within the crystal structure and high-pressure annealing had a minimal efect on the phonon modes in the rhombohedral phase, but the magnetic properties were improved in comparison to pristine BiFeO&sub(3) . The impact of chemical modifcations and high-pressure annealing on the suppression of spin cycloid and the appearance of weak ferromagnetism was discussed.
