Lack of coupling between superconductivity and orthorhombic distortion in stoichiometric single-crystalline FeSe
A. E. Böhmer, F. Hardy, F. Eilers +5
The coupling between superconductivity and othorhombic distortion is studied in vapor-grown FeSe single crystals using high-resolution thermal-expansion measurements. In contrast t…
Magnetic properties of single-crystalline CeCuGa3
Devang A. Joshi, P. Burger, P. Adelmann +7
The magnetic behavior of single-crystalline CeCuGa3 has been investigated. The compound forms in a tetragonal BaAl4-type structure consisting of rare-earth planes separated by Cu-G…
Thermal expansion and Grüneisen parameters of Ba(Fe1-xCox)2As2 - a thermodynamic quest for quantum criticality
Christoph Meingast, Frédéric Hardy, Rolf Heid +7
Thermal expansion data are used to study the uniaxial pressure dependence of the electronic/magnetic entropy of Ba(Fe1-xCox)2As2. Uniaxial pressure is found to be proportional to d…
Doping evolution of superconducting gaps and electronic densities of states in Ba(Fe1-xCox)2As2 iron pnictides
F. Hardy, P. Burger, T. Wolf +9
An extensive calorimetric study of the normal- and superconducting-state properties of Ba(Fe1-xCox)2As2 is presented for 0 < x < 0.2. The normal-state Sommerfeld coefficient increa…
Phonon spectrum and soft-mode behavior of MgCNi_3
R. Heid, B. Renker, H. Schober +3
Temperature dependent inelastic neutron-scattering measurements of the generalized phonon density-of-states for superconducting MgCNi_3, T_c=8 K, give evidence for a soft-mode beha…
High-Resolution Thermal Expansion of MgB2
R. Lortz, C. Meingast, D. Ernst +3
The thermal expansion of polycrystalline MgB2 from 5-300 K is studied using high-resolution capacitance dilatometry. The thermal expansivity exhibits a small jump of -5.8x10-8 K-1…
