Changing the magnetic states of an Fe/BaTiO interface through crystal field effects controlled by strain.

The search for better and inexpensive magnetoelectric materials is now commonplace in solid state physics. Intense coupling between technologically viable electric and magnetic properties, embedded in a single material, is still an attribute greatly pursued by the scientific community. Following this line of thought, using DFT, the study of a specific interface between the TiO layer of BaTiO and a monolayer of Fe atoms is presented, probing different uni-axial strain effects of the considered supercell.
