Es. Grinberg et al., TL2-FIELD APPLICATION STUDY OF FERROELECTRICS AND ANTIFERROELECTRICS PARTS OF MIXED RB1-X(NH4)XH2PO4 - SYSTEM PHASE-DIAGRAM( EPR WITH ELECTRIC), Ferroelectrics. Letters section, 15(3-4), 1993, pp. 61-68
The results of the detailed study of the freezing process in the disor
ded ferro- and antiferroelectric RADP compounds by means of the Tl2+ E
PR have been presented. The data obtained show that the distribution o
f the frozen local fields arises and broadens in these compounds in th
e smeared manner similar to that found earlier for the glassy compound
s, in spite of the presence of the long range order at low temperature
s.
