Magnetization reversal of perpendicular magnetic anisotropy regulated by ferroelectric polarization in CoFe3N/BaTiO3 heterostructures: first-principles calculations

Ferroelectric polarization reverses the magnetic anisotropy of FeN–TiO 2 and FeCo–BaO configurations, which is mainly due to the strong magnetoelectric coupling and orbital hybridization between the interfacial Fe/Co atoms and O atoms.
