Abstract

В работе Ваниной П. Ю. выявлено существование двух разных типов диффузного рассеяния в монокристалле Sr0,6Ba0,4Nb2O6 в релаксорном состоянии, и определены соответствующие корреляционные длины. Получены температурные зависимости намагниченности и параметры магнитных фазовых переходов (ФП) в монокристаллах мультиферроиков La0,875Sr0,125MnO3 и La0,93Sr0,07MnO3. Выявлено влияние размерных эффектов и внешних воздействий на сегнетоэлектрические ФП в нанокомпозитных материалах (НКМ) на основе магнитных и немагнитных щелочно-боросиликатных стекол (ЩБС), содержащих (1-x)KH2PO4 – (x)(NH4)H2PO4 и KH2PO4. Также установлен критический размер наночастиц нитрата калия, полученных при внедрении в пористые ЩБС, при котором стабильность сегнетоэлектрического состояния в НКМ не зависит от температурной предыстории образцов.
