Electrical spectrum of CoCr$_2$S$_{3.5}$Se$_{0.5}$

It has been shown that, at temperatures of 140–300 K in the frequency range from 0.065 to 6 Hz, the permittivities $\varepsilon'$ and $\varepsilon''$ of CoCr$_2$S$_{3.5}$Se$_{0.5}$ increase with an increase in the temperature according to the law $\varepsilon_i=a^i_1+a^j_2\exp(-\Delta x_i/kT)$. As the frequency increases, the permittivity decreases. An analysis has demonstrated that the main polarization mechanism is the orientation polarization.
