“…When cooling under an applied electric field, a long time is required to reach the equilibrium value of that effective field. In this sense, it has been suggested previously that the nucleation process and the resulting domain pattern are sensitive to the temperature variation rate [11,12].…”

The para-ferroelectric tricritical phase transition of a single crystal of triglycine selenate (TGSe) has been studied in the neighbourhood of the transition temperature, under weak electric fields, E, using a highly sensitive calorimetric technique. The specific heat, cE, under fields in the range between 5 and 175 V cm−1 and close to transition temperature (0.2 K), shows different behaviour on cooling and on heating at a temperature variation rate of ± 0.03 K h−1; for T

“…Ratio of the long-and short axes of the ellipse perpendicular to spontaneous polarization direction ͑ b axis of crystal coordinate͒ is ϳ5. 5,26 Doping ␣-alanine in TGS ͑LATGS͒ induces an internal electric field that polarizes crystals to a monodomain state, but its influence on the Curie temperature T C is little, and T C shifts to higher temperature by only ϳ1 K. [15][16][17][18] All TGS and LATGS samples used in dielectric measurements are prepared as platelets with sizes being aϫbϫcϭ5ϫ0.6ϫ5 mm 3 , and each b surface was coated with silver by evaporation.…”

The temperature dependence of the dielectric constant and dissipation in potassium dihydrogen phosphate ͑KDP͒, its deuterated compound ͑DKDP͒, triglycine sulfate ͑TGS͒, and TGS doped with ␣-alanine ͑LATGS͒ has been studied at various frequencies. It is found that the relaxation time of domain freezing in KDP and DKDP in the kHz range can be described by the Vogel-Fulcher relation. Evidence of domain freezing in TGS is presented through an analysis of relaxation time related to domain walls and a comparison between TGS and LATGS. Studies of internal friction and compliance show preliminary evidence of domain freezing in CuAlZnNi alloy. A domain-freezing model is proposed based upon the collective pinning of randomly distributed pinning centers to domain walls. Some key experiments related to domain freezing, such as ͑1͒ the Vogel-Fulcher relation for relaxation time; ͑2͒ the size effect of domain freezing; ͑3͒ two kinds of relaxation in low-and high-frequency ranges, respectively; and ͑4͒ the dependence of T F on defect density and applied field, etc., are explained. ͓S0163-1829͑97͒01323-4͔
