The question of the interface is a key issue in multi-ferroïc heterostructures. Hybridization between filled d orbitals responsible for magnetization and empty d orbitals in the ferroelectric oxide may be one path to such coupling. Several coupling mechanisms have been identified and these can be quite complex. For example, the charge ordering of a magnetic layer can be modulated by the polarization state of an adjacent ferroelectric.
