Temperature and size dependence of the elementary excitation of the layered ferroics (ferroelectrics or ferromagnetics) are calculated using the functional integral method and XZ Heisenberg model within the Gaussian approximation. Basing on this result, the other thermodynamic properties like specific heat, polarization…are obtained. A comparision with experimental and other theoretical results for typical ferroics is carried out and discussed.
