摘要：

The temperature dependences of the specific heat and the thermal conductivity of crystalline superionic conductors LnF(3) (Ln = La, Ct, Pr), Li2B4O7 and alpha-LiIO3 in the superionic phase have been investigated experimentally, The specific heat C-p ansi the thermal conductivity K are observed to increase monotonically over a wide range of temperatures above the Debye temperature Theta(D). This increase is attributed to the relaxational interaction of high-frequency phonons with two-level systems. (C) 1997 American Institute of Physics.
