摘要：

A simple epitaxial heterostructure of NiFe2O4-BaTiO3 grown on (001)-SrTiO3 substrate was prepared via pulsed laser deposition. Structural characterization by x-ray diffraction and electron microscopy showed good horizontal heterostructure of (001)-NiFe2O4 parallel to(001)-BaTiO3 epitaxially grown on the substrate, which presents simultaneously strong ferroelectric and ferromagnetic responses at room temperature. In particular, an obvious direct magnetoelectric coupling was observed in the heterostructured film, which provides a convincing measurement of the direct magnetoelectric effect in the multiferroic nanostructures.
