Phonon Raman scattering of RCrO3 perovskites (R = Y, La, Pr, Sm, Gd, Dy, Ho, Yb, Lu)
M. Weber, J. Kreisel, P. A. Thomas +3
We report a systematic investigation of orthorhombic perovskite-type RCrO3 powder samples by Raman scattering for nine different rare earth R3+ cations (R = Y, La, Pr, Sm, Gd, Dy,…
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…
Strain analysis of multiferroic BiFeO3-CoFe2O4 nanostructures by Raman scattering
O. Chaix-Pluchery, C. Cochard, P. Jadhav +4
We report a Raman scattering investigation of columnar BiFeO3-CoFe2O4 (BFO-CFO) epitaxial thin film nanostructures, where BFO pillars are embedded in a CFO matrix. The feasibility…
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…
