Specific heat and thermal conductivity of a single crystal-like Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+x} high-Tc superconductor
- Shanghai Jiao Tong Univ. (China)
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 Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+x} is selected as the sample, and its specific heat is measured by adiabatic calorimetry, 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 {Delta}C / C {approx} 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.
