Charge-driven complex oxide multiferroics

Materials that display a coupling between ferroelectric and magnetic ordering form an attractive platform to study the fundamental physical processes that determine the interplay between different physical properties and for the development of new applications using multifunctional materials.

In this context, our demonstration of a direct, charge-mediated magnetoelectric coupling in a novel multilayer system (see Figure) opens a new vista for the development of novel magnetoelectric devices with large charge coupling between electric and magnetic degrees of freedom.
