The behavior of polarization of a Ba0.8Sr0.2TiO3 thin film in an external electric field for a planar geometry of electrodes is described using a simple phenomenological model. The “van der Waals field” E z formed by the substrate along the normal to the film surface is introduced for fitting to experimental data. This field is estimated as E z = 1.1 × 108 V/m. The phase diagram of the Ba0.8Sr0.2TiO3 film in the E z (misfit strain) at room temperature is analyzed.
