Отдел кристаллофизики

Заведующий отделом — Тер-Оганесян Никита Валерьевич, д.ф.-м.н., г.н.с.

Общая информация:

Отдел кристаллофизики проводит фундаментальные и прикладные исследования структуры, фазовых состояний и функциональных свойств кристаллических материалов. Основные научные интересы отдела связаны с сегнетоэлектриками и антисегнетоэлектриками, пьезоэлектриками, магнитоэлектриками и мультиферроиками, а также с изучением магнитных явлений и взаимосвязи структуры, электрической и магнитной подсистем кристалла. 

Особое внимание уделяется фазовым переходам, атомному и катионному упорядочению, механизмам возникновения электрической поляризации и магнитоэлектрического эффекта, а также исследованию диэлектрических, пьезоэлектрических и магнитных свойств керамик, монокристаллов и тонких плёнок. Теоретические исследования включают феноменологическую теорию фазовых переходов, симметрийный анализ, квантово-химические и первопринципные расчёты, молекулярно-динамическое моделирование и методы Монте-Карло.

Одним из современных направлений работы отдела является создание и исследование средне- и высокоэнтропийных материалов, в частности оксидов со структурой перовскита. Изучаются условия их синтеза, фазовая стабильность, особенности катионного упорядочения, кристаллическая структура и функциональные свойства.
