Abstract

The specific heat in (KBr)1−x(KCN)x has been measured for concentrations 0.00≦x≦0.93 and for temperatures 2 K≦T≦50 K. In addition, the dipolar relaxation phenomena were studied using dielectric spectroscopy. The relaxation behaviour was parametrized assuming a Gaussian distribution of energy barriers and the mean activation energies, the distribution widths, and the attempt frequencies have been determined as a function of the CN concentration. With these parameters the linear and the excess specific heat contributions were calculated and compared to the calorimetric results.

    Guided by the interpretation of low-T specific heat data (T≲ 2K) it became standard to describe the excess term by aT 3 dependence. However, the results of a number of glasses revealed that the excess contributions have a more complex temperature dependence and appear as a bump in aC/T 3 versusT plot. In (NaCN)1−x(KCN)x glassy solids theT 3 range extends toT≈6 K with no evidence of an excess bump; see Mertz, B., Berret, J.F., Böhmer, R., Loidl, A., Meissner, M., Knaak, W.: Phys. Rev.
