Abstract
Composite structures based on ferroelectric BaTi 0.85Sn 0.15O 3 and Ba 0.996Y 0.004TiO 3 substrates and La 0.775Sr 0.225MnO 3 films deposited on them, which have a perovskite structure, have been prepared. The effect of different methods of film deposition on the properties of films has been studied. A detailed analysis and comparison of electrophysical properties and structure of ceramic and film ferromagnetics prepared by different methods has been carried out. The effect of the chemical composition of the substrate on the temperature of phase transition in manganite films has been studied. The possibility to control the magnetoresistivity of ferromagnetic films by electric field has been shown.
