Phase diagram and dielectric properties of mixed Cs1-x(NH4)(x)H2PO4 crystals
Baranov, A. I.; Dolbinina, V. V.; Lanceros-Méndez, S.; Schmidt, V. H.Influence of NH4-->Cs substitution has been studied in the mixed Cs1-x(NH4)(x)H2PO4 crystals system by means of dielectric measurements. The x-T phase diagram was determined: for ammonium concentrations up to 0.1 the system has a monoclinic paraelectric phase with a transition into a ferroelectric phase whose temperature increases with increasing ammonium concentration. For ammonium concentration 0.4 to 1.0 the...
