520			\|a In order to elucidate a dipolar-glassy state realized in the solid-solution system of PyH(BF4)1− x (PF6) x (Py = C5NH5) at low temperatures, we investigated thermal properties of the solid solutions by adiabatic calorimetry. The solid solutions with the compositions x = 0.18, 0.51, and 0.89 exhibited enthalpy relaxations characteristic of glass transitions respectively between 30 and 90 K. The enthalpy relaxation time of 103 s at the glass transition temperature was well reproduced by the temperature dependence of dielectric relaxation times obtained by dielectimetry for each solid-solution sample. The result indicates that the calorimetrically observed glass transition is the dipolar-glass transition, and the dipolar-glassy state is revealed to be a thermodynamically non-equilibrium state where the configuration of the electric dipoles are frozen in by slowing down of the thermally activated reorientational motion of the dipoles.

The solid solutions with the compositions x = 0.18, 0.51, and 0.89 exhibited enthalpy relaxations characteristic of glass transitions respectively between 30 and 90 K. The enthalpy relaxation time of 103 s at the glass transition temperature was well reproduced by the temperature dependence of dielectric relaxation times obtained by dielectimetry for each solid-solution sample. The result indicates that the calorimetrically observed glass transition is the dipolar-glass transition, and the dipolar-glassy state is revealed to be a thermodynamically non-equilibrium state where the configuration of the electric dipoles are frozen in by slowing down of the thermally activated reorientational motion of the dipoles.

abstract	In order to elucidate a dipolar-glassy state realized in the solid-solution system of PyH(BF4)1− x (PF6) x (Py = C5NH5) at low temperatures, we investigated thermal properties of the solid solutions by adiabatic calorimetry. The solid solutions with the compositions x = 0.18, 0.51, and 0.89 exhibited enthalpy relaxations characteristic of glass transitions respectively between 30 and 90 K. The enthalpy relaxation time of 103 s at the glass transition temperature was well reproduced by the temperature dependence of dielectric relaxation times obtained by dielectimetry for each solid-solution sample. The result indicates that the calorimetrically observed glass transition is the dipolar-glass transition, and the dipolar-glassy state is revealed to be a thermodynamically non-equilibrium state where the configuration of the electric dipoles are frozen in by slowing down of the thermally activated reorientational motion of the dipoles.
