Photoemission study of the electronic structure (Pr0.2La0.8)(Ba1.875La0.125)Cu3O7-gd


Journal Article

Photoemission results from the Pr and La doped 1 2 3 system (Pr0.2La0.8) (Ba1.875La0.125)Cu3O7-gd are reported. The core level spectra show strong resemblance to those of other compounds of the 1 2 3 and 2 1 4 systems. The Cu 2p satellite intensity is found to be ∼ 35% of the main Cu 2p line, and the O 1s core level spectra, exhibiting a clear doublet, show evidence of extrinsic oxygen. The clear correlation between the intensities of certain features in the valence band and the amount of extrinsic oxygen, as monitored by the O 1s core level spectra, is explicitly addressed. © 1989.
