Abstract
Measurements of isothermal relaxation of nonequilibrium a.c. conductivity f or the pure triglycine sulphate (TGS) and TGS doped with chromium have been made after fast cooling from the paraelectric phase to the ferroelectric o ne. The influence of the cooling rate and a d.c. electric field on the appe arance and relaxation of metastable states below the Curie point was observ ed. A possible mechanism of these phenomena is discussed in frame of a mode l of interaction between point defects and domain walls.
