Using ab-initio simulations, we investigated the effects of ferroelectricpolarization on the magnetic anisotropy of FePt/BaTiO3heterojunctions. The changed electronic structure at the interface of FePt and BaTiO3 reduced the magnetic anisotropy energy (MAE) under ferroelectricpolarization. Through the electronic density of states analysis, it was found that the MAE change is mainly due to the changed hybridization state between d-orbitals of interface Ti and Fe atoms.
