abstract BaTiO3 is a well-known ferroelectric material, with an electric field-induced coupled electrical/structural transition from a cubic to a tetragonal lattice above room temperature. Via DFT calculations, the magnetic properties of an Fe monolayer sandwiched between bulk-like BaTiO3 are explored, showing how the magnetic moment of each Fe atom is switched from a null spin to a high spin (2 mu(B) per Fe) state when the BaTiO3 structure changes from cubic to tetragonal. This effect occurs in an optimized range of interatomic distances at the interface, allowing the design of an above-room temperature binary, electric field write/magnetic read device.
