title = "Pressure-induced phase transition and phonon softening in",
abstract = "We combine diamond anvil cell techniques, synchrotron-based infrared and Raman scattering spectroscopies, a symmetry analysis, and complementary lattice dynamics calculations to explore the pressure-driven phase transition in multiferroic . Comparison of the measured and predicted phonon patterns reveals a structural transition at 15 GPa. Symmetry breaking across the polar antipolar transition takes place via changes in the bipyramidal tilting direction and Lu/Sc displacement pattern, analogous to the strain-driven distortion pathway in and temperature-induced transitions in the rare-earth manganites.",
