Abstract

The electrical resistivity of NdBa₂(Cu_1-ZZn_Z)₃O_7-Y as a function of temperature from 4.2K to room temperature and the thermal conductivity of the samples in the temperature range from 4.2K to 120K have been measured. As is consistent with the most previous reports, it shows that the thermal conductivity of the samples exhibit a peak at a temperature below T_c. The thermal conductivity of the electrons can be calculated from the resistivity of sample, which is rather small than the experimental results of the samples. Therefore, the main heat carriers are believed to be phonons. Then the measured thermal conductivity was separated into electron and phonon contributions, and the phonon thermal conductivity were analyzed by using the theory of Tewordt-Wolkhausen.
