Development of methods for the production of new nanostructured multiferroics based on simple and ternary transition metal oxides to achieve large magnetoelectric (ME) coupling at room temperatures, development and testing of a new concept of creating nanostructured oxide multiferroics with a large magnetoelectric effect based on the coexistence of super paramagnetic and ferroelectric phases.

 The technology for obtaining the initial components of three-phase composite materials - nanopowders stoichiometric and with oxygen defects Fe3O4 and ferromagnetic micropowder based on a PbZr0,53Ti0,47O3 (PZT) solid solution - was developed. The technology for manufacturing a composite based on Fe3O4 nanopowder, PZT micropowder with PVDF polymer binder has been developed to study the magnetoelectric properties of this combination of superparamagnetic and ferroelectric particles. For samples of PVDF-PZT-Fe3O4 composite materials, Po -oE hysteresis loops are observed, caused by the ferrophase, which is formed due to the presence of PZT in the composite structure. An increase in Fe3O4 content is accompanied by a decrease in residual polarization and an increase in the loss tangent, which is associated with the formation of percolation paths between Fe3O4 particles in the dielectric matrix.
