Abstract
We have measured the temperature dependence of the in-plane thermal conductivity, κab(T), for both Er-Ba-Cu-O and Ho-Ba-Cu-O superconducting bulks. The absolute values of κab(T) for both bulks are smaller than that of Y-Ba-Cu-O bulk, but are larger than that of Dy-Ba-Cu-O bulk, which is known to show an anomalous small κab. κab(T) for Ho-Ba-Cu-O shows a positive slope (dκab/dT>0) in the normal state, similarly to that for Dy-Ba-Cu-O. On the other hand, a slightly negative slope (dκab/ dT<0) is found for Er-Ba-Cu-O. The out-of-plane thermal conductivity, κc, was also measured for Er-Ba-Cu-O bulk, and the anisotropy in the thermal conductivity, (κab/κc), was estimated to be about 2.
