Magnetoelectric coupling in multiferroic heterostructures (B02)

• Subject Area: Theoretical Condensed Matter Physics ; Experimental Condensed Matter Physics
• Term: from 2008 to 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 31047526

This project concentrates on the theoretical understanding of the magnetoelectric coupling at the interface of a ferroelectric oxide with a magnetic material. We focus on (i) the specific modification of the metallization at an oxide-oxide interface by the ferroelectric polarization or the magnetization as well as on first-principles calculations of (ii) ballistic transport in metaloxide- metal tunnel junctions with four conductance states and (iii) the tunnel anisotropic magnetoresistance due to the spinorbit interaction. We aim at predict-ing and demonstrating phenomena that can be switched by external fields.
