Abstract
This paper reports on the results of the investigation into the temperature and time behavior of the parameters of the domain structure in nominally pure and doped (α-alanine, chromium, phosphorus) triglycine sulfate crystals, which has been revealed by piezoresponse force microscopy during observation of the domain structure. The relaxation time dependences on the total perimeter of the domain walls, the velocity of lateral domain-wall motion, and the coefficient of static unipolarity have been obtained using computer image processing of the domain structure of the crystals under investigation. The temperature dependences of these parameters near the Curie temperature have been found. A comparison with the data available in the literature has been made, as well as with the results of our measurements of the permittivity for the same samples and under the same temperature-time conditions.
