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…
High-pressure phase transitions in BiFeO3: hydrostatic vs. non-hydrostatic conditions
Mael Guennou, Pierre Bouvier, Raphaël Haumont +2
We report high-pressure x-ray diffraction experiments on BiFeO3 (BFO) single crystals in diamond-anvil cells up to 14 GPa. Two data sets are compared, one in hydrostatic conditions…
