Abstract

We have measured the thermal conductivity (κ) of bulk Y-Ba-Cu-O blocks welded with sintered Er-Ba-Cu-O and Y-Ba-Cu-O/Ag at temperatures between 5 and 300 K. For comparison, the thermal conductivity was also measured for melt-textured Y-Ba-Cu-O and Er-Ba-Cu-O. All the samples showed the enhancement of κ at around 50 K, which was commonly observed in high temperature superconductors. The maximum κ values were 90 mW/cm K for both welded Y-Ba-Cu-O and melt-textured Er-Ba-Cu-O and 150 mW/cm K for melt-textured Y-Ba-Cu-O. Such differences have originated from different microstructural features.
