摘要：

The electronic structure of the single crystals La0.74Ba0.26Mn1-yCoyO3 (y = 0.12, 0.16, 0.22) has been investigated with X-ray photoelectron spectroscopy (XPS). The transition-metal core level spectra, as well as the valence band (VB) spectra, were studied. By analyzing the valence band spectra we have determined that the Co 3d contribution to the VB of Co-doped single crystals La0.74Ba0.26Mn1-yCOyO3 ranges from approximately 1.0 to 4.5 eV bindin energy. Co 2p core level spectra indicate a divalent character of the Co ions. (C) 2003 Elsevier Science B.V. All rights reserved.
