Superconductivity of Electron-Doped NdOBiS2 by Substitution of Mixed-Valence Ce ions
Naoki Kase, Masaya Matsumoto, Katsuo Kondo +4
Superconductivity is achieved in Nd1-xCexOBiS2 via electron doping using mixed-valence Ce ions. Single crystals with x = 0.2, 0.3, 0.4, and 0.5 are generated using a CsCl flux meth…
Syntheses and First-Principles Calculations of the Pseudobrookite Compound AlTi2O5
Takami Tohyama, Riku Ogura, Kensuke Yoshinaga +3
We synthesize a new titanium-oxide compound AlTi2O5 with pseudobrookite-type structure. The formal valence of Ti is 3.5+ that is the same as the Magneli compound Ti4O7 and the spin…
Coexistence of superconductivity and charge-density wave in the quasi-one-dimensional material HfTe3
Saleem J. Denholme, Akinori Yukawa, Kohei Tsumura +6
We present the first experimental evidence for metallicity, superconductivity (SC) and the co-existence of charge density waves (CDW) in the quasi-one-dimensional material HfTe3. T…
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…
Itinerancy and Electron Correlation in FeSe 1-x Superconductor Studied by Bulk-Sensitive Photoemission Spectroscopy
A. Yamasaki, S. Imada, K. Takase +9
We have investigated the electronic structures of newly discovered superconductor FeSe1-x by bulk-sensitive photoemission spectroscopy (PES). The large Fe 3d spectral weight is loc…
Single Junction and Intrinsic Josephson Junction Tunneling Spectroscopies of Bi2Sr2CaCu2O8+d
L. Ozyuzer, C. Kurter, J. F. Zasadzinski +3
Tunneling spectroscopy measurements are reported on optimally-doped and overdoped BiSrCaCuO single crystals. A novel point contact method is used to obtai…
