Abstract
In the present work the relaxational processes of polarization reversal in deuterated triglycine sulphate crystals (DTGS) were studied under the condition of electric external field commutation. The effects of the electric field magnitude and direction on the switching processes in DTGS were studied at different temperatures. It is shown that the decrease of ε obeys the empirical rule of Kohlrausch ε(t)∼exp(t/τav)α) (τav is the average relaxation time and α is a constant, 0<α≤1) in a wide range of temperature and field. For the DTGS crystal it is valid to use a set of relaxation times. The constant α is function of the external field and temperature.
