B2: Magnetoelectric coupling in multiferroic heterostructures
In this project, we study the microscopic origins of the magnetoelectric coupling of the magnetic and electronic degrees of freedom for two-component multiferroic systems. Two-component multiferroic systems are hybrid structures, made of a ferroelectric and a magnetic layer that are connected by a common interface. Typical samples combine ferroelectric oxides with ferromagnetic oxides or ferromagnetic metals.
One essential aspect of the project is the interaction of the electric polarization within the ferroelectric layer with the properties of a metallic cover layer, which in particular is caused by the spin-orbit interaction. The properties of interest comprise the spin Hall effect, the anomalous Hall effect, and the Rashba-Bychkov splitting. We expect that a change of the polarization direction modifies the spin-orbit coupling and, thus, for example the direction of a spin current.
