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…
Electronic structure of pristine and K-doped solid picene: Non-rigid-band change and its implication for electron-intramolecular-vibration interaction
H. Okazaki, T. Wakita, T. Muro +11
We use photoemission spectroscopy to study electronic structures of pristine and K-doped solid picene. The valence band spectrum of pristine picene consists of three main features…
Electron correlation in FeSe superconductor studied by bulk-sensitive photoemission spectroscopy
A. Yamasaki, Y. Matsui, S. Imada +18
We have investigated the electronic structures of recently discovered superconductor FeSe by soft-x-ray and hard-x-ray photoemission spectroscopy with high bulk sensitivity. The la…
Superconducting and Structural Transitions in the β-Pyrochlore Oxide KOs2O6 under High Pressure
Hiroki Ogusu, Nao Takeshita, Koichi Izawa +5
Rattling-induced superconductivity in the β-pyrochlore oxide KOs2O6 is investigated under high pressure up to 5 GPa. Resistivity measurements in a high-quality single crystal revea…
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…
Pressure-induced changes in the magnetic and valence state of EuFe2As2
K. Matsubayashi, K. Munakata, N. Katayama +9
We present the results of electrical resistivity, ac specific heat, magnetic susceptibility, X-ray absorption spectroscopy (XAS) and X-ray magnetic circular dichroism (XMCD) of the…
