REPOLARIZATION OF CRYSTALS OF ROCHELLE-SALT GROUP UNDER WEAK, INTERMEDIATE, AND STRONG ELECTRIC FIELDS OF LOW AND INFRALOW FREQUENCIES

摘要

We studied the repolarization of crystals of the Rochelle-salt group at low and infralow frequencies. The measurement was carried out at temperatures equidistant from the upper and lower phase transitions for virtually identical P_s in a wide range of amplitudes of measurement fields (E_0 = 7 - 500 V·cm~(-1)). The results are discussed in terms of interaction of domain walls with point defects and changes in the characteristic (most probable) frequencies of relaxation of repolarization of crystals.
