Ab Initio Characterization of Magnetoelectric Coupling in Fe/BaTiO3, Fe/SrTiO3, Co/BaTiO3 and Co/SrTiO3 Heterostructures

Magneto-electric coupling is a desirable property for material used in modern electronic devices to possess due the favorable possibilities of tuning properties using magnetic field and vice versa. However, such materials are rare nature. That why so-called superlattice approach creating receiving so much attention. In approach, functionality combined heterostructure depends on interacting components can be adjusted depending desired property. present paper, we supercells ferromagnetic thin films Fe Co deposited ferroelectric piezoelectric substrates BaTiO3 SrTiO3 that exhibit magnetism, polarization effects. Within structures under investigation, moments tuned by an external electric via dipoles. We investigate effect magnetoelectric means ab initio spin-polarized spin–orbit calculations. study structural, heterostructures, show electrostriction reduce magnitude magnetization vector ferromagnet. This become basis controlling one layers superconducting spin valve, thus valve.
