Abstract
The structural, electronic and magnetic properties of interfaces between epitaxial La0.7Sr0.3MnO3 and PbTiO3 have been explored via atomic resolution transmission electron microscopy of a functional multiferroic tunnel junction. Measurements of the polar displacements and octahedral tilting show the competition between the two distortions at the interface, and demonstrate a strong dependence on the polarisation orientation. Density functional theory provides information on the electronic and magnetic properties, where the interface termination plays a crucial role in the screening mechanisms.
