Abstract

Measurements on the temperature variation of the thermal conductivity, thermopower and electrical resistivity of a superconducting Y-Ba-Cu-O compound are reported. The results, which are qualitatively interpreted in terms of the ordinary electronic and phonon transport theory applied to superconducting metallic alloys, suggest that the strong electron-phonon coupling should be considered in the interpretation of superconductivity in these materials.
