SUPERCONDUCTING AND NORMAL STATE THERMAL CONDUCTIVITY IN HIGH CRITICAL TEMPERATURE YBACUO(X) PELLETS.

Author(s) : NOTO K.

Type of article: Article

Summary

THE THERMAL CONDUCTIVITY OF SUPERCONDUCTING YBACUO(X) (X ABOUT 6.9) PELLET AND NONSUPERCONDUCTING YBACUO(X) (X ABOUT 6.3) PELLET WAS SUTDIED BETWEEN 1. 8 AND 200 K. ELECTRONIC THERMAL CONDUCTIVITY TURNED OUTTO BE ABOUT 10-20% OF THE TOTAL CONDUCTIVITY. THEREFORE, THE ENHANCEMENT OF THE CONDUCTIVITY IN SUPERCONDUCTING SAMPLE BELOW CRITICAL TEMPERATURE IS THOUGHT TO COME FROM THE PHONON CONDUCTION ENHANCEMENT DUE TO THE REDUCTION OF NORMAL ELECTRONS BELOW CRITICAL TEMPERATURE, SINCE THE PHONON CONTRIBUTION IS DOMINATED IN THESE SAMPLES.
