Abstract
  • We have investigated the temperature-dependent changes in the near-E-F occupied and unoccupied states of Pr0.67Ca0.33MnO3 which shows the presence of ferromagnetic and antiferromagnetic phases. The temperature-dependent changes in the charge and orbital degrees of freedom and associated changes in the Mn 3d-O 2p hybridization result in varied O 2p contributions to the valence band. A quantitative estimate of the charge transfer energy (E-CT) shows a larger value compared to the earlier reported estimates. The charge localization causing the large E-CT is discussed in terms of different models including the electronic phase separation. (literal)
