Spectroscopic Evidence for Electron-Boson Coupling in Half-metallic CrO2
Daiki Ootsuki, Hirokazu Fujiwara, Noriyuki Kataoka +9
We report quasiparticle properties of the half-metal ferromagnet CrO2 by means of high-resolution angle-resolved photoemission spectroscopy (ARPES). We clearly observed the Fermi s…
Anomalously large spin-dependent electron correlation in nearly half-metallic ferromagnet CoS
Hirokazu Fujiwara, Kensei Terashima, Junya Otsuki +19
The spin-dependent band structure of CoS which is a candidate for a half-metallic ferromagnet was investigated by both spin- and angle-resolved photoemission spectroscopy and t…
Weak antilocalization induced by Se substitution in layered BiCh-based (Ch = S, Se) superconductors LaOFBiSSe
Kazuhisa Hoshi, Hiroto Arima, Noriyuki Kataoka +6
We report transport properties for layered BiCh2-based (Ch = S, Se) superconductors LaO1-xFxBiS2-ySey (x = 0.2, 0.5, y = 0-1.05) and the observation of weak antilocalization (WAL).…
Soft x-ray irradiation induced metallization of layered TiNCl
Noriyuki Kataoka, Masashi Tanaka, Wataru Hosoda +5
We have performed soft x-ray spectroscopy in order to study the photoirradiation time dependence of the valence band structure and chemical states of layered transition metal nitri…
μ-PES Studies on TiNCl and Quasi-two-dimensional Superconductor Na-intercalated TiNCl
Noriyuki Kataoka, Kensei Terashima, Masashi Tanaka +5
Electron-doped TiNCl is a superconductor, for which exotic mechanisms of the superconductivity have been discussed. However, difficulty in preparing large single-phase samples has…
Enhanced thermoelectricity by controlled local structure in bismuth-chalcogenides
K. Terashima, Y. Yano, E. Paris +7
Spectroscopic techniques, including photoelectron spectroscopy, diffuse reflectance, and x-ray absorption, are used to investigate the electronic structure and the local structure…
