(La0.7Sr0.3MnO3)m(BiFeO3)n superlattices were grown in situ on SrTiO3(001) substrates by rf magnetron sputtering. The current-voltage measurements were performed under the temperature of 50—150℃ for the superlattices specimens. The analysis showed that the leakage current increased with increasing the temperature or decreasing the BFO thickness in the samples. And the conduction mechanisms of the prepared (La0.7Sr0.3MnO3)m(BiFeO3)n superlattices were analyzed according to common insulator conduction models. It exhibited that the space-charge-limited current were dominated in the as fabricated (La0.7Sr0.3MnO3)m(BiFeO3)n superlattices in high temperature or high electrical field.
