Composition Effect on Glass-Like Properties of Mixed Crystals of KDP Type with Competing Interaction
Publikováno v:
Ferroelectrics. 299:133-144
The analysis of dielectric and polarization properties of mixed ferroantiferroelectric crystals (1 −x )KDP-xADP and related systems has been performed for broad range of concentration x. The problems concerning the composition effect on spontaneous

Ferroelectric phase transition was detected in monoclinic RbD2 PO4 at TC3 =313K in addition to the known antiferroelectric phase transition at TC2 =319K. The almost saturated value of the spontaneous polarisation is about Psy = 6.10−4 μC/cm2 at 28
