Chemical modifcation is an efective method for obtaining functional materials with desired properties for technological applications. In this work, the highpressure prepared BiFeO3 compounds with partial substitution of Bi by Tb ions were studied. The microstructures, phonon modes, and macroscopic magnetic properties of the Bi1−xTbxFeO3 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 BiFeO3 . The impact of chemical modifcations and high-pressure annealing on the suppression of spin cycloid and the appearance of weak ferromagnetism was discussed.
