Functional integral method is employed to calculate thermodynamic properties of thin ferroic (ferromagnetic or ferroelectric) films within the framework of a transverse Ising model. The conventional mean field approximation for free energy and for equation of states is carried out with higher-order correction by using Gaussian approximations. We also analyze the dependence of fluctuations of the order parameter on temperature and on the thickness of thin films.
