主　　题：oxide heterointerfaces asymmetric interfacial effects ferromagnetic order charge transfer 

摘      要：Interfacial magnetism in functional oxide heterostructures not only exhibits intriguing physical phenomena but also implies great potential for device *** these systems,interfacial structural and electronic reconstructions are essential for improving the stability and tunability of the magnetic *** this work,we constructed ultra-thinLa_(0.67)Ca_(0.33)MnO_(3)/SrRuO_(3)(SRO)layers into superlattices,which exhibited a robust ferromagnetic *** high Curie temperature(TC)reaches 291 K,more than 30 K higher than that of bulk *** found that the LCMO/SRO superlattices consisted of atomically-sharp and asymmetric *** a unique interface structure can trigger a sizable charge transfer as well as a ferroelectric-like polar *** two interfacial effects cooperatively stabilized the high-T_(C)ferromagnetic *** results could pave a promising approach towards effective control of interfacial magnetism and new designs of oxide-based spintronic devices.
