Title: New mechanism of electro-magnetic coupling in composite multiferroics
Abstract: Composite multiferroics – materials with strong coupling between electric and magnetic degrees of freedom are the main topic of research in condensed matter physics and materials science. These materials show non-trivial fundamental physical properties and are promising candidates for numerous applications. In this talk I will discuss a new mechanism of magneto-electric coupling appearing in composite multiferroics due to the interplay of strong Coulomb interaction and ferroelectricity. This mechanism leads to the unusual magnetic phase diagram with the ordered magnetic phase appearing at higher temperatures than the magnetically disordered phase. The mechanism allows the electric field control of magnetic properties and magneto-transport in composite multiferroics.
