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
Competition between magnetism and superconductivity in rare-earth nickel boride carbides.
Hiroshi Eisaki,Hidenori Takagi,Robert J. Cava,Bertram Batlogg,J. J. Krajewski,W. F. Peck,K. Mizuhashi,J. O. Lee,S. Uchida +8 more
TL;DR: In this article, the competition between magnetism and superconductivity was investigated for the recently discovered R${\mathrm{Ni}}_{2}$${B}}-C superconductors with the magnetic rare-earth elements R=Tm,Er,Ho,Dy.
Journal ArticleDOI
Observation of Spin-Charge Separation in One-Dimensional SrCuO2.
Changyoung Kim,A. Y. Matsuura,Zhi-Xun Shen,Naoki Motoyama,Hiroshi Eisaki,S. Uchida,Takami Tohyama,Sadamichi Maekawa,Sadamichi Maekawa +8 more
TL;DR: Angle-resolved photoemission data from one-dimensional SrCuO{sub 2} compounds are found to be qualitatively different from that of two- dimensional Sr{ sub 2}CuO}, and the two underlying bands having approximately 1.2 and 0.3eV energy dispersion are identified.
Journal ArticleDOI
Magnetic Susceptibility of Ideal Spin 1 / 2 Heisenberg Antiferromagnetic Chain Systems, Sr 2 CuO 3 and SrCuO 2
TL;DR: The results are in excellent agreement with the recent calculation by Eggert, Affleck, and Takahashi, and an isotropic susceptibility drop is observed below about 20 K, which is consistent with the result of this rigorous calculation.
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.
