摘要	We report the synthesis and characterization of an epitaxial heterostructure composed of multiferroic BiFeO(3) and superconducting YBa(2)Cu(3)O(7-delta) thin films grown on (001) SrTiO(3). Both the superconductivity of YBa(2)Cu(3)O(7-delta) and the ferroelectricity of BiFeO(3) are retained in the heterostructure. Current density-electric field characteristics measured from 30 to 170 K suggest a Schottky-emission-like transport at the BiFeO(3)/YBa(2)Cu(3)O(7-delta) interface. Furthermore, the temperature dependence of the barrier height shows an anomalous enhancement at T(C), indicating an intimate coupling between the multiferroic and the superconducting layers.
