Manipulating magnetoelectric properties by interfacial coupling in La_0.3Sr_0.7MnO₃/Ba_0.7Sr_0.3TiO₃ superlattices.

ABSTRACT: Artificial superlattices constructed with ferromagnetic La_0.7Sr_0.3MnO₃ layer and ferroelectric Ba_0.7Sr_0.3TiO₃ layer were designed and fabricated on SrTiO₃ substrates. An epitaxial growth with sharp interfaces between La_0.7Sr_0.3MnO₃ and Ba_0.7Sr_0.3TiO₃ layers was confirmed by scanning transmission electron microscopy and x-ray diffraction. An unambiguous charge transfer involving an electron transferring from the La_0.7Sr_0.3MnO₃ layers to Ba_0.7Sr_0.3TiO₃ layers (Mn³⁺→Mn⁴⁺; Ti⁴⁺→Ti³⁺) across the interface were resolved by electron energy loss spe
