Dielectric properties of Cst.Sr(CH,CH.C00). (DSP), Ca,Sr(CH.CH.C00),..-.,(HCF.CF.C00)..(HCF.CF.-DSP) and Ca.Sr(CH.CH.C00)... .,(HCF.C00),.(HCF.-DSP) crystals have been studied in the terrvperature range from 4 K to roomtemperature at several freque.ncies between l and 100 kHz. The DSP crystal under-went I-II, II-III and III-IV phase transitions near 281.2, 76 and 58 K, respectively. InHCF.CF.-DSP and HCF.-DSP crystals, the phase transition temperature decreasedfor the I-II phase transition and increased for the II-INN phase transition with the in-crease in the content of HCF.CF.C00/HCF.C00 ton (.v). These results werequalitatively explained by the motion of propionate group associated with the phasetransitions.
