M. Abbate,F. M. F. de Groot,J. C. Fuggle,Atsushi Fujimori,O. Strebel,F. Lopez,M. Domke,G. Kaindl,George A. Sawatzky,Mikio Takano,Yasuo Takeda,Hiroshi Eisaki,S. Uchida +12 more
TL;DR: In this paper, a comparison between the transition-metal 2p spectra and atomic-multiplet calculations is used to determine the 3d count of holes induced by substitution for both series are located in states of mixed metal 3d--oxygen 2p character.
Journal ArticleDOI
Electronic structure of La1-xSrxMnO3 studied by photoemission and x-ray-absorption spectroscopy
Tomohiko Saitoh,A. E. Bocquet,Takashi Mizokawa,Hirofumi Namatame,A. Fujimori,M. Abbate,Yasuo Takeda,Mikio Takano +7 more
TL;DR: In this paper, the electronic structure of the Mn 2p core levels and the valence bands of the O 1s x-ray-absorption spectroscopy has been analyzed using a configuration-interaction cluster model.
Journal ArticleDOI
Possibility for an intermediate-spin ground state in the charge-transfer material SrCoO3
TL;DR: In this paper, the possibility of an intermediate-spin ground state for a Co 2p x-ray absorption spectroscopy spectrum was discussed, where the ground state is stabilized by the relative stability of the ligand hole state that it hybridizes with using atomic multiplet calculations.
Journal ArticleDOI
Electronic-structure and spin-state transition of lacoo3
M. Abbate,J. C. Fuggle,A. Fujimori,Liu Hao Tjeng,C. T. Chen,R. Potze,George A. Sawatzky,Hiroshi Eisaki,S. Uchida +8 more
TL;DR: The O 1s XAS spectra reflect important changes in the unoccupied Co 3d bands across the spin-state transition, and indicate a gradual transition to a mixed-spin state in LaCoO3.
Journal ArticleDOI
Electronic structure and temperature-induced paramagnetism in LaCoO 3
TL;DR: In this article, the electronic structure of the Co 2p LaCoO was studied by photoemission spectroscopy and x-ray absorption spectro-composition (XAS) spectra.
