| Abstract: | The d.c. conductivity of NaKSO4 crystal is investigated, along various crystallographic axes in the temperature range from 300 to 500 K. Two segments are observe in the temperature dependence of electric conductivity at Tc=453 K. The spontaneous strain η1s, η2s and η3s, deduced from measurements of the linear thermal expansion coefficients along various crystallographic axes a, b and c showed linear temperature dependence below the transition temperature. |
