Abstract
Studying electrocaloric effect (ECE) in ferroelectrics is interesting both for fundamental investigations and for engineering applications and for adequate description of thermodynamic thermal physical parameters of ferroelectric films. The present paper introduces a theoretical approach developed on the basis of Landau-Chalatnikov model that allows describing not only the presence of dynamic spontaneous polarization but also its influence on the character of temperature dependence of EC-effect.
