Description	Many perovskites exhibit very high dielectric permittivity which is of great practical interest in applications. Its origin consists in anomalous lattice dynamics, which has been little investigated. Recently it has been demonstrated that in real systems (en) Řada perovskitů vykazuje velice vysokou dielektrickou permitivitu, což představuje velký aplikační zájem. Její původ spočívá v anomální mřížkové dynamice, která byla dosud málo zkoumána. Nedávno bylo ukázáno, že v reálných systémech pro aplikace, tj. v t
