Ambient temperature thermal conductivity of YBa₂Cu₃O_{7 - x}

A comparative method was used to measure the thermal conductivity λ of a YBa₂Cu₃O_7-x sample over the temperature range 305-360 K. Using one sample, data were obtained at two different x levels. Surprisingly, the smaller x value (higher T_c) produced a lower thermal conductivity. This observation is discussed in terms of scattering of phonons by point defects and electrons.
