Abstract
The thermal conductivities of single-crystal Li, Na, K, and Ag -alumina have been measured in the temperature range of K. The thermal conductivity is very sensitive to the cation present and is indicative of a broad band of excitations (J, Hz) which scatter thermal phonons. The results are compared with a tunneling-states theory of disordered materials and with published data from specific-heat and light-scattering measurements.
