Abstract
Thermal-conductivity measurements have been used to study the temperature dependence of the scattering of phonons and electrons in single crystals of the superconducting layer compound Nb between 1 and 10 K. In this temperature range, the results agree with standard theoretical models for a three-dimensional metal. The magnetoresistance has a very strong linear magnetic-field dependence as might be expected if there were magnetic breakdown at superzone gaps induced by charge-density waves.
