Stability of the tetragonal phase of BaZrO3 under high pressure
Constance Toulouse, Danila Amoroso, Robert Oliva +8
In this paper, we revisit the high-pressure behavior of BaZrO3 by a combination of first-principle calculations, Raman spectroscopy, and x-ray diffraction under high pressure. We c…
Structural and lattice-dynamical properties of Tb2O3 under compression: a comparative study with rare-earth and related sesquioxides
Jordi Ibáñez, Juan Ángel Sans, Vanesa Cuenca-Gotor +9
We report a joint experimental and theoretical investigation of the high-pressure structural and vibrational properties of terbium sesquioxide (Tb2O3). Powder x-ray diffraction and…
Lattice dynamics and Raman spectrum of BaZrO3 single crystals
Constance Toulouse, Danila Amoroso, Cong Xin +7
BaZrO3 is a perovskite that remains in the simple cubic phase at all temperatures, hence with no first-order Raman-active phonon mode allowed by symmetry. Yet, it exhibits an inten…
