Lattice dynamics and Raman spectrum of supertetragonal PbVO3
Pierre Bouvier, Alireza Sasani, Eric Bousquet +2
Lead vanadate PbVO3 is a polar crystal with a P4mm space group at ambient conditions. It is isostructural with the model soft-mode driven ferroelectric PbTiO3, but differs from it…
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 properties and Raman spectra of columbite-type NiNbVO synthesized under high pressure
Jully P. Peña, Pierre Bouvier, Oliver Isnard
The complete set of structural parameters of the new series of compounds NiNbVO () with the unusual columbite-type structure is presented here. In t…
Jahn-Teller, polarity and insulator-to-metal transition in BiMnO3 at high pressure
Mael Guennou, Pierre Bouvier, Pierre Toulemonde +5
The interaction of coexisting structural instabilities in multiferroic materials gives rise to intriguing coupling phenomena and extraordinarily rich phase diagrams, both in bulk m…
Multiple high-pressure phase transitions in BiFeO3
Mael Guennou, Pierre Bouvier, Grace S. Chen +4
We investigate the high-pressure phase transitions in BiFeO3 by single crystal and powder x-ray diffraction, as well as single crystal Raman spectroscopy. Six phase transitions are…
Structural investigation of LaAlO3 up to 63 GPa
Mael Guennou, Pierre Bouvier, Gaston Garbarino +1
We report a high-pressure single-crystal synchrotron x-ray diffraction on a LaAlO3 single crystal. The transition from rhombohedral to cubic at 14.8 GPa is confirmed by the loss of…
