Modern progress in science and technology is inextricably linked with the development of scientific knowledge in the field of composite materials. An important place among the known functional composite materials is occupied by magnetostrictive-piezoelectric materials, whose unique properties are due to the existence of a magnetoelectric (ME) effect in them. In such materials, the value of the ME coefficients is several orders of magnitude higher than their value in single-phase ME materials, which makes it possible to widely apply the ME effect in practice. To optimize the ME parameters, an urgent task is to study the relationship between the magnetic, electrical, and ME properties of such structures. By present time, a large number of magnetostrictive-piezoelectric composites based on ferromagnetic metals, ferrites and various types of piezoceramics have been studied theoretically and experimentally. The need for such research comes from the needs of modern mobile communication technology, Internet communications, television and radio broadcasting, radio navigation equipment and other electronic equipment in new devices based on new functional materials. A significant number of works are devoted to the research of new ME materials, including multiferroic materials [1] Multiferroic materials - materials in which two or more types of “ferro” ordering coexist simultaneously: ferromagnetic, ferroelectric and ferroelastic have broad prospects for application in energy collection systems [2– 7].
