摘要 | Iron resonant valence band photoemission spectra (VB PES) of Sr substituted LaFe0.75Ni0.25O3-delta have been recorded across the Fe 2p-3d absorption threshold to obtain Fe specific spectral information on the 3d projected partial density of states. Comparison with La1-xSrxFeO3 resonant VB PES literature data suggests that substitution of Fe by Ni forms electron holes which have mainly O 2p character. Substitution of La by Sr increases the hole concentration to an extent that the e(g) structure vanishes. The variation in the e(g) and t(2g) structures is paralleled by the changes in the electrical conductivity. (C) 2010 American Institute of Physics. ()[doi: 10.1063/1.3484960] |
