An experiment was conducted to show that an LSMO 2DEG emerges at the interfaces of [(La0.7Sr0.3MnO3/SrTiO3] 8 (LSMO/STO) superlattices grown in the (001) direction. Calculations of resistivity in a model system including spin-orbit coupling reveal that the inplane peak is due to transport through a two-dimensional (2D) system at the manganite interface. Density Functional Theory (DFT+U) calculations confirm that the 2D system results from a FM and metallic interfacial manganite layer antiferromagnetically coupled (A-type) to the rest of the LSMO. The X-ray absorption experiments clearly indicate an in-plane orbital polarization of the interfacial e g Mn electrons. Such magnetic modification could be related to the spin depolarization revealed by tunneling magnetoresistance measurements in manganite based tunneling devices. X-ray magnetic circular dichroism and EELS measurements have revealed a small charge transfer to Ti giving rise to a magnetic moment which is anti-parallel to that on the Mn sites.
