Crossover between liquid-like and gas-like behaviour in CH4 at 400 K
D. Smith, M. A. Hakeem, P. Parisiades +10
We report experimental evidence for a crossover between a liquid-like state and a gas-like state in fluid methane (CH4). This crossover is observed in all of our experiments, up to…
Exploration of the Hg-based cuprate superconductors by Raman spectroscopy under hydrostatic pressure
N. Auvray, B. Loret, S. Chibani +8
The superconducting phase of the (Hg-1201) and (Hg-1223) cuprates has been investi…
Isotope effect on the E2g phonon and mesoscopic phase separation near the electronic topological transition in Mg1-xAlxB2
L. Simonelli, V. Palmisano, M. Fratini +5
We report the boron isotope effect on the E2g phonon mode by micro-Raman spectroscopy on the ternary Mg1-xAlxB2 system, synthesized with pure isotopes 10B and 11B. The isotope coef…
Pressure-Temperature phase diagram of multiferroic EuTiO
P. Parisiades, E. Liarokapis, J. Köhler +2
The structural transformation of multiferroic EuTiO has been intensively investigated by synchrotron x-ray diffraction at pressures up to 50.3 GPa and temperatures from 50 to 5…
