| Popis: | Measurements of isothermal relaxation of nonequilibrium a.c. conductivity for the pure triglycine sulphate (TGS) and TGS doped with chromium have been made after fast cooling from the paraelectric phase to the ferroelectric one. The influence of the cooling rate and a d.c. electric field on the appearance and relaxation of metastable states below the Curie point was observed. A possible mechanism of these phenomena is discussed in frame of a model of interaction between point defects and domain walls. |
