- Abstract
- The electronic structure of ferromagnetic double-perovskite La2MnNiO6 has been investigated by employing Mn and Ni 2p -> 3d resonant photoemission spectroscopy (RPES) and soft x-ray absorption spectroscopy (XAS). The Mn and Ni 2p XAS measurements show that Mn ions are formally tetravalent (3d(3)) and that Ni ions are formally divalent (3d(8)). Mn and Ni 2p -> 3d RPES shows that the occupied Mn 3d(3) (t(2g)(3)up arrow) states are sharp and located around 2 eV below E-F, while the occupied Ni 3d(8) (t(2g)(3)up arrow t(2g)(3)up arrow e(g)(2)up arrow) states are broader than the Mn 3d states and they extend from E-F to similar to 5 eV below E-F.
