Temperature-Dependence of Magnetically-Active Charge Excitations in Magnetite across the Verwey Transition
M. Taguchi, A. Chainani, S. Ueda +16
We have studied the electronic structure of bulk single crystals and epitaxial films of magnetite FeO. Fe core-level spectra show clear differences between hard x-ray…
Electronic structure of an antiferromagnetic metal: CaCrO3
P. A. Bhobe, A. Chainani, M. Taguchi +11
We report on the electronic structure of the perovskite oxide CaCrO3 using valence-band, core-level, and Cr 2p - 3d resonant photoemission spectroscopy (PES). Despite its antiferro…
Evidence for a correlated insulator to antiferromagnetic metal transition in CrN
P. A. Bhobe, A. Chainani, M. Taguchi +15
We investigate the electronic structure of Chromium Nitride (CrN) across the first-order magneto-structural transition at T_N ~ 286 K. Resonant photoemission spectroscopy shows a g…
Evidence for Oxygen Holes due to d-p Rehybridization in Thermoelectric Sr_{1-x}Rh_{2}O_{4}
Y. Ishida, T. Baba, R. Eguchi +8
Soft-x-ray photoemission and absorption spectroscopies are employed to investigate the electronic structures of Sr_{1-x}Rh_{2}O_{4}. Similarly to the layered cobaltates such as Na_…
Fermi surfaces, electron-hole asymmetry and correlation kink in a three-dimensional Fermi liquid LaNiO
R. Eguchi, A. Chainani, M. Taguchi +6
We report the three-dimensional (3-D) momentum-resolved soft x-ray photoemission spectroscopy of the Fermi liquid LaNiO. The out-of-plane and in-plane cuts of the 3-D electron-…
Anomalous State Sandwiched between Fermi Liquid and Charge Ordered Mott-Insulating Phases of Ti4O7
M. Taguchi, A. Chainani, M. Matsunami +15
The Magneli phase Ti4O7 exhibits two sharp jumps in resistivity with coupled structural transitions as a function of temperature at Tc1=142 K and Tc2=154 K. We have studied electro…
Revisiting the valence-band and core-level photoemission spectra of NiO
M. Taguchi, M. Matsunami, Y. Ishida +10
We have re-examined the valence-band (VB) and core-level electronic structure of NiO by means of hard and soft x-ray photoemission spectroscopy (PES). The spectral weight of the lo…
Photoemission evidence for a Mott-Hubbard metal-insulator transition in VO
R. Eguchi, M. Taguchi, M. Matsunami +15
The temperature () dependent metal-insulator transition (MIT) in VO is investigated using bulk sensitive hard x-ray ( 8 keV) valence band, core level, and V 2 re…
Evidence for mass renormalization in LaNiO$"" sub 3_: an in situ soft x-ray photoemission study of epitaxial films
K. Horiba, R. Eguchi, M. Taguchi +5
We investigate the electronic structure of high-quality single-crystal LaNiO (LNO) thin films using in situ photoemission spectroscopy (PES). The in situ high-resolution soft x…
