Description
We present thermal conductivity measurements on the layered perovskite superconductor Sr2RuO4 down to very low temperatures (20 mK). Our data show a large residual term in κ/T as T → 0 K which depends on the sample quality. We do not observe any sign of the predicted crossover at low temperatures or of a second phase transition at least above 20 mK. (author). Letter-to-the-editor
