摘要：

The glass transition in (NH4I)(x)(KI)(1-x) has been studied using dielectric spectroscopy. The (x,T) phase diagram reveals three different glassy regions, g(1), g(2), and g(3). The dynamical susceptibility in the regime g(2) reveals a power-law dependence on frequency, epsilon* proportional to A(T)omega(s(T)). The experimental results are compared with theoretical models and provide evidence for the near-equilibrium dynamics in an orientational glass.
