Abstract

We report the synthesis and characterization of an epitaxial heterostructure composed of multiferroic BiFeO₃ and superconducting YBa₂ Cu₃ O_7-δ thin films grown on (001) SrTiO₃. Both the superconductivity of YBa₂ Cu₃ O_7-δ and the ferroelectricity of BiFeO₃ 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 / YBa₂ Cu₃ O_7-δ 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. © 2010 American Institute of Physics.
