Ab initio study of magnetoelectricity in Fe/BaTiO3: the effects of n-doped perovskite interfaces

On the basis of ab initio calculations we study the interfacial magnetoelectric effect in a prototypical biferroic Fe(L)/XO2/BaO/BaTiO3(001) (X = Ti, V, Co), with an Fe thickness L ≤ 2 monolayers. We anticipate that the use of the n-type perovskite termination instead of nominally neutral TiO2 may e...

Zusammenfassung:On the basis of ab initio calculations we study the interfacial magnetoelectric effect in a prototypical biferroic Fe(L)/XO2/BaO/BaTiO3(001) (X = Ti, V, Co), with an Fe thickness L ≤ 2 monolayers. We anticipate that the use of the n-type perovskite termination instead of nominally neutral TiO2 may enhance magnetoelectricity in the system when its magnetization is robustly changed by substrate-polarization reversal.
