Description	V článku je prezentována metoda pro identifikaci procesů, které jsou zodpovědné za stárnutí dielektrických vlastností feroelektrických materiálů. Metoda je založena na analýze vývoje lineární a nelineární permitivity během stárnutí. Použitelnost metody je demonstrována na čtyřech scenáriích dielektrického stárnutí ve dvou kvalitativně odlišných systémech. (cs) In this Article, there is presented a method for the identification of the process, which is responsible for the ferroelectric ageing. The method is based on the analysis of the evolution of both the linear and nonlinear permittivity during ageing. Applicability of the method is theoretically demonstrated on four ageing scenarios in two qualitatively different systems where the evolution of the nonlinear permittivity is controlled, first, by a redistribution of the pinning centers on the domain wall and, second, by microstructural changes at the interface between the ferroelectric layer and the electrode. It is shown that each ageing scenario is characterized by unique trend in the evolution between the linear and nonlinear part of the permittivity, which can be verified experimentally.
