Effect of the isoelectronic substitution of Sb for As on the magnetic and structural properties of LaFe(As1-xSbx)O
S. J. E. Carlsson, F. Levy-Bertrand, C. Marcenat +9
The antiferromagnetic order and structural distortion in the LaFe(As1-xSbx)O system have been investigated by powder neutron diffraction and physical properties measurements. Polyc…
Direct observation of the influence of the FeAs4 tetrahedron on superconductivity and antiferromagnetic correlations in Sr2VO3FeAs
Gaston Garbarino, Ruben Weht, Amadou Sow +7
We measure the pressure dependence of the electrical resistivity and the crystal structure of iron superconductor Sr2VO3FeAs. Below ~10 GPa the structure compresses but remains und…
The direct relation between the coefficient of the low temperature resistivity T^2 term and the superconducting transition temperature Tc
Manuel Núñez-Regueiro, Gastón Garbarino, María Dolores Núñez-Regueiro
In several superconductors above the superconducting transition temperature Tc, the electrical resistivity is of the form ρ =AT^2. We show that there exists an empirical relation b…
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…
