Direct evidence for charge leakage at the interface of epitaxial SrTiO 3 /LaMnO 3 superlattices with atomically sharp interfaces is provided. The direction of charge leakage can be reversed by changing the LMO/STO thickness ratio. This result will be important for the understanding of some of the reported limitations of oxide devices involving manganite/titanate interfaces.
