Abstract
The characteristics of specific heat and thermal conductivity for high — Tc superconductors are discussed. In order to understand the behaviors of a high-Tc superconductor, a single crystal-like Bi2Sr2CaCu2O8+x is selected as the sample, and its specific heat is measured by adiabatic calorimeter, while its thermal conductivity is measured by steady heat flow method via a stainless steel radiation shield. The measured specific heat C of the crystal shows a jump at Tc with ΔC/C ≈ 3.5%, while the measured thermal conductivity in the ab plane shows a minimum value at Tc which is qualitatively in good agreement with other work. The measuring skills are specially analyzed. In addition, the thermal expansion coefficient for the crystal-like high-Tc superconductor is also shown.
