On the Origin of the Double Superconducting Transition in Overdoped YBa2Cu3Ox
R. Lortz, T. Tomita, Y. Wang +4
The superconducting transition in a single overdoped, detwinned YBa2Cu3Ox (YBCO) crystal is studied using four different probes. Whereas the AC and DC magnetic susceptibilities fin…
Evolution of the specific-heat anomaly of the high-temperature superconductor YBa2Cu3O7 under influence of doping through application of pressure up to 10 GPa
Rolf Lortz, Alain Junod, Didier Jaccard +4
The evolution of the specific-heat anomaly in the overdoped range of a single crystal of the high-temperature superconductor YBa2Cu3O7 has been studied under influence of pressure…
Modulated-bath AC calorimetry using modified commercial Peltier-elements
Rolf Lortz, Satoko Abe, Yuxing Wang +3
We developed a new type of AC microcalorimeter based on a modulated-bath technique for measuring the specific heat of small microgram samples in the temperature range from 30-300 K…
Specific heat, magnetic susceptibility, resistivity and thermal expansion of the superconductor ZrB12
R. Lortz, Y. Wang, S. Abe +4
In an attempt to clarify conflicting published data, we report new measurements of specific heat, resistivity, magnetic susceptibility, and thermal expansivity up to room temperatu…
Specific heat and magnetization of a ZrB12 single crystal: characterization of a type II/1 superconductor
Yuxing Wang, Rolf Lortz, Yuriy Paderno +4
We measured the specific heat, the magnetization, and the magnetoresistance of a single crystal of ZrB12, which is superconducting below Tc ~ 6 K. The specific heat in zero field s…
Reversible and irreversible magnetocaloric effect in the NdBa_2Cu_3O_7 superconductor in relation with specific heat and magnetization
T. Plackowski, Y. Wang, R. Lortz +2
A recently developed technique for measuring the isothermal magnetocaloric coefficient () is applied to the study of a superconducting NdBaCuO single crystal. Resu…
