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…
Photoemission Evidence for Valence Fluctuations and Kondo Resonance in YbAl2
M. Matsunami, A. Chainani, M. Taguchi +9
We use hard x-ray photoemission spectroscopy (HAXPES) to investigate the electronic structure of YbAl2, for which the Yb valence has not been consistently reported to date. The bul…
Nanoscale Dichotomy of Ti 3d Carriers Mediating the Ferromagnetism in Co:TiO2 Anatase Thin Films
T. Ohtsuki, A. Chainani, R. Eguchi +11
We study the surface and bulk electronic structure of the room-temperature ferromagnet Co:TiO2 anatase films using soft and hard x-ray photoemission spectroscopy with probe sensiti…
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…
Strong valence fluctuation in the quantum critical heavy fermion superconductor beta-YbAlB4: A hard x-ray photoemission study
M. Okawa, M. Matsunami, K. Ishizaka +12
Electronic structures of the quantum critical superconductor beta-YbAlB4 and its polymorph alpha-YbAlB4 are investigated by using bulk-sensitive hard x-ray photoemission spectrosco…
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…
