The obtained O 1s spectra within the photon energy 529-535 eV can be decomposed into eg↑1, e g↑2, t2g↓, and eg↓ bands. Based on the assigned energy levels of these band states, the energies of magnetic exchange, crystal field and Jahn-Teller (JT) splitting are determined. Particularly, the JT splitting is around 0.8 eV, which is observed with O 1s XAS for the first time in NCMO thin films. © 2010 American Institute of Physics. |
