Dielectric properties of the magnetoelectric composites (x)PbZr0.53Ti0.47O3 (1-x)Mn0.4Zn0.6Fe2O4 [(x)PZT − (1-x)MZF] with x = 0.2, 0.6, 0.7, 0.8, 0.9, and 1.0 have been studied at frequencies from 200 Hz to 50 kHz in a temperature range of the diffuse ferroelectric phase transition (FPT). It is established that FPT becomes more diffuse as the PZT constituent in composites is decreased. Diffuseness of the FPT in composites is explained in terms of the Isupov-Smolenskii model
На частотах от 200 Гц до 50 кГц изучены диэлектрические свойства магнитоэлектрических композитов (x)PbZr0,53Ti0,47O3 (1-x)Mn0,4Zn0,6Fe2O4 [(x)PZT − (1-x)MZF] с x = 0,2; 0,6; 0,7; 0,8; 0,9 и 1 в области температур сегнетоэлектрического фазового перехода (СФП). Установлено, что уменьшение содержания PZT в композитах приводит к увеличению размытия СФП. Размытие СФП в композитах объясняется в рамках модели Исупова-Смоленского
