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,…
Structural and insulator-to-metal phase transition at 50 GPa in GdMnO3
J. Agostinho Moreira, A. Almeida, J. Oliveira +6
We present a study of the effect of very high pressure on the orthorhombic perovskite GdMnO3 by Raman spectroscopy and synchrotron x-ray diffraction up to 53.2 GPa. The experimenta…
Magentically-Induced Lattice Distortions and Ferroelectricity in Magnetoelectric GdMnO3
J. Agostinho Moreira, A. Almeida, J. Oliveira +4
In this work we investigate the magnetic field dependence of Ag octahedra rotation (tilt) and B2g symmetric stretching modes frequency at different temperatures. Our field-dependen…
Large area quasi-free standing monolayer graphene on 3C-SiC(111)
Camilla Coletti, Konstantin V. Emtsev, Alexei A. Zakharov +3
Large scale, homogeneous quasi-free standing monolayer graphene is obtained on cubic silicon carbide, i.e. the 3C-SiC(111) surface, which represents an appealing and cost effective…
Thulium and ytterbium-doped titania thin films deposited by MOCVD
Sébastien Forissier, Hervé Roussel, Carmen Jimenez +5
In this study we synthesized thin films of titanium oxide doped with thulium and/or ytterbium to modify the incident spectrum on the solar cells. This could be achieved either by p…
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…
Phase transition close to room temperature in BiFeO3 thin films
J. Kreisel, P. Jadhav, O. Chaix-Pluchery +4
BiFeO3 (BFO) multiferroic oxide has a complex phase diagram that can be mapped by appropriately substrate-induced strain in epitaxial films. By using Raman spectroscopy, we conclus…
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…
Direct observation of the influence of the As-Fe-As angle on the Tc of superconducting SmFeAsOF
G. Garbarino, R. Weht, A. Sow +7
The electrical resistivity, crystalline structure and electronic properties calculated from the experimentally measured atomic positions of the compound SmFeAsOF…
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…
