Study of tunneling impurities in alkali halides at low temperatures
The impurity tunneling systems of Li+ in KCl and CN-in KBr have been studied by means of specific heat (C) and thermal expansion (a) measurements obtained at temperatures T between 0.09 K and 10 K. For the Li+ defects, a peak occurs in the thermal expansion near 1 K which is qualitatively similar …
