The paper describes the results of studies of the dielectric, magnetic and structural properties of the multiferroic films. We have investigated two ways of forming multiferroic media –first of them based on multilayer film structures containing ferroelectric and ferromagnetic films and the second by the introduction of the magnetic elements in ferroelectric films in concentrations sufficient to cause magnetic properties. The most promising material for multilayer ferrite-ferroelectric are ferroelectrics based on perovskite solid solutions in particular barium strontium titanate BaxSr1-xTiO3 (BSTO), and ferrites of iron garnet Y3Fe5O12 (YIG). This article has been shown experimentally that the relationship between electric and magnetic subsystems (magnetoelectric effect) allows to modify the dielectric properties by the magnetic field in layered structures Cu-Cr/BSTO/YIG/GGG.
