The dielectric response of triglycine selenate at frequencies of 0.07Hz-10MHz in the paraelectric phase

The behavior of triglycine selenate single crystal in the paraelectric phase (above the phase transition temperature) was experimentally studied with the dielectric spectroscopy method in this work. The results of investigation of electrical properties were given in the frequency range from 0.07Hz to 10MHz and in the temperature interval from 7 to 70C. The presence of non-Debye spectrum type and linear dispersion that reveal in the paraelectric phase too was marked. One suggests that the linear dispersion is connected with proton multiposition hopping conductivity.
