ABSTRACT The temperature dependences during heating and cooling processes of the dielectric properties of the metal- dielectric-semiconductor (MDS) structure based on ferroelectric Ba0,8Sr0,2TiO3 films deposited on silicon substrates (n-type 3KEF and p-type 4KDB) by high-frequency sputtering in the crystallographic direction (100) are studied in the temperature range 300- 440 K. Several relaxation-type phase transitions associated with the ferroelectric property of these crystals are discovered. Keywords: ferroelectric film, metal-dielectric- semiconductor, heating, cooling, dielectric constant, dielectric loss tangent.
