Abstract :
Results of a study of the dielectric, magnetic, and structural properties of films with multiferroic properties are reported. Two ways to form multiferroic media are analyzed, by fabrication of multilayer structures containing films of ferroelectrics and ferromagnetics and by introduction of magnetic elements into a ferroelectric in concentrations sufficient for magnetic properties to appear in the composite material. The possibility of tuning the device in the microwave and high-frequency ranges is experimentally confirmed.
