Abstract

We report on the electronic properties of superlattices composed of three different antiferromagnetic insulators, NdMnO₃/SrMnO₃ / LaMnO₃ grown on SrTiO₃ substrates. Photoemission spectra obtained by tuning the x-ray energy at the Mn 2p→3d edge show a Fermi cut-off, indicating metallic behavior mainly originating from Mn e_g electrons. Furthermore, the density of states near the Fermi energy and the magnetization obey a similar temperature dependence, suggesting a correlation between the spin and charge degrees of freedom at the interfaces of these oxides.
