The magnetic properties and electronic structures of SMO_n/LAO_m are investigated by density functional theory calculations to reveal the magnetic ground states and novel interfacial spin transport properties. Both n-type LaO/MnO₂ and p-type SrO/AlO₂ interface show metallicity, and the density of states of Mn and O play the crucial role. It is demonstrated that we can tailor the electronic properties by applying epitaxial strain and adding the external magnetic field. This paper aims to provide an in-depth understanding of the origin of interfacial metallic and shed light on designing next-generation electronic devices.
