Abstract
Measurements of the hysteresis loop and longitudinal electric susceptibility were carried out on a triglycineselenate [(NH2CH2COOH)3H2SeO4] single crystal in the form of a round plate with an additional side electrode. The remanentpolarization was initially reduced to zero due to a prolonged application of anelectric voltage between the measurement and the side electrodes. Next, aftervoltage disconnection, a gradual transition from the crystal state characterizedby the zero remanent polarization to the original state was investigated whilealternately increasing and decreasing temperature. The remanent polarizationstarted to noticeably increase each time the heating was interrupted and the crystalstarted to be cooled. The experimental data showed that the triglycine selenate(TGSe) crystal then behaved in such a way as if it ‘remembered’ the maximaltemperature to which it had been heated after switching off the voltage. Suchmemory was also observed in the case of the longitudinal electric susceptibilitymeasurements. A freezing parameter was introduced in order to describe the experimentaldata.
