Anisotropy, disorder, and superconductivity in CeCu2Si2 under high pressure
A. T. Holmes, D. Jaccard, H. S. Jeevan +2
Resistivity measurements were carried out up to 8 GPa on single crystal and polycrystalline samples of CeCu2Si2 from differing sources in the homogeneity range. The anisotropic res…
Spin and Valence-Fluctuation Mediated Superconductivity in Pressurized Fe and CeCu2(Si/Ge)2
D. Jaccard, Alexander T. Holmes
We review the evidence supporting valence-fluctuation mediated superconductivity in CeCu2Si2 and CeCu2Ge2, where Tc reaches 2.4 K at high pressure. In these systems the valence and…
On the thermoelectricity of correlated electrons in the zero-temperature limit
Kamran Behnia, Didier Jaccard, Jacques Flouquet
The Seebeck coefficient of a metal is expected to display a linear temperature-dependence in the zero-temperature limit. To attain this regime, it is often necessary to cool the sy…
Probing the phase diagram of CeRu_2Ge_2 by thermopower at high pressure
H. Wilhelm, D. Jaccard
The temperature dependence of the thermoelectric power, S(T), and the electrical resistivity of the magnetically ordered CeRu_2Ge_2 (T_N=8.55 K and T_C=7.40 K) were measured for pr…
Unconventional superconductivity and normal state properties of epsilon-iron at high pressure
A. T. Holmes, D. Jaccard, G. Behr +2
Following the discovery of superconductivity in epsilon-iron, subsequent experiments hinted at non-Fermi liquid behaviour of the normal phase and sensitive dependence of the superc…
Signatures of valence fluctuations in CeCu2Si2 under high pressure
A. T. Holmes, D. Jaccard, K. Miyake
Simultaneous resistivity and a.c.-specific heat measurements have been performed under pressure on single crystalline CeCu2Si2 to over 6 GPa in a hydrostatic helium pressure medium…
