A high-pressure Raman study of polycrystalline samples of BaCexZr1−xO3 is performed at room temperature. The evolution of Raman spectra with pressure is compared to the evolution of the Raman spectra of BaZrO3 and BaCeO3. The effect of composition on the pressure-induced phase transitions is monitor...
