Influence of hydrostatic pressure on the bulk magnetic properties of EuIrO
G. Prando, R. Dally, W. Schottenhamel +7
We report on the magnetic properties of EuIrO upon the application of hydrostatic pressure by means of macroscopic and local-probe techniques. In contrast to…
Strong enhancement of conventional superconductivity near a quantum critical point of (Ca,Sr)_3Ir_4Sn_13
P. K. Biswas, Z. Guguchia, R. Khasanov +5
Competing electronic states are found in the large majority of unconventional superconductors, including high-Tc cuprates, iron based superconductors and many heavy fermion systems…
Direct evidence for the emergence of a pressure induced nodal superconducting gap in the iron-based superconductor Ba_0.65Rb_0.35Fe_2As_2
Zurab Guguchia, Alex Amato, Jian Kang +10
Identifying the superconducting (SC) gap structure of the iron-based high-temperature superconductors (Fe-HTS's) remains a key issue for the understanding of superconductivity in t…
Oxygen Isotope Effects on Lattice Properties of La_{2-x}Ba_xCuO_4 (x = 1/8)
Z. Guguchia, D. Sheptyakov, E. Pomjakushina +6
A novel negative oxygen-isotope (16O/18O) effect (OIE) on the low-temperature tetragonal phase transition temperature T_{LTT} was observed in La_{2-x}Ba_xCuO_4 (x = 1/8) using high…
Mutual independence of critical temperature and superfluid density under pressure in optimally electron-doped superconducting LaFeAsOF
G. Prando, Th. Hartmann, W. Schottenhamel +9
The superconducting properties of LaFeAsOF in conditions of optimal electron-doping are investigated upon the application of external pressure up to kbar. M…
