Localized and mixed valence state of Ce in superconducting and ferromagnetic CeOFBiS revealed by x-ray absorption and photoemission spectroscopy
T. Sugimoto, D. Ootsuki, E. Paris +11
We have performed Ce -edge x-ray absorption spectroscopy (XAS) and Ce - resonant photoemission spectroscopy (PES) on single crystals of CeOFBiS for $x=…
Direct observation of nanoscale interface phase in the superconducting chalcogenide KFeSe with intrinsic phase separation
A. Ricci, N. Poccia, B. Joseph +13
We have used scanning micro x-ray diffraction to characterize different phases in superconducting KFeSe as a function of temperature, unveiling the thermal evolut…
Coexistence of localized and itinerant electrons in BaFe2X3 (X = S and Se) revealed by photoemission spectroscopy
D. Ootsuki, N. L. Saini, F. Du +4
We report a photoemission study at room temperature on BaFe2X3 (X = S and Se) and CsFe2Se3 in which two-leg ladders are formed by the Fe sites. The Fe 2p core-level peaks of BaFe2X…
Temperature dependence of iron local magnetic moment in phase-separated superconducting chalcogenide
L. Simonelli, T. Mizokawa, M. Moretti Sala +6
We have studied local magnetic moment and electronic phase separation in superconducting KFeSe by x-ray emission and absorption spectroscopy. Detailed temperature…
Effect of Pt substitution on the electronic structure of AuTe2
D. Ootsuki, K. Takubo, K. Kudo +12
We report a photoemission and x-ray absorption study on Au1-xPtxTe2 (x = 0 and 0.35) triangular lattice in which superconductivity is induced by Pt substitution for Au. Au 4f and T…
Coexistence of Bloch electrons and glassy electrons in Ca10(Ir4As8)(Fe2_xIrxAs2)5 revealed by angle-resolved photoemission spectroscopy
K. Sawada, D. Ootsuki, K. Kudo +9
Angle-resolved photoemission spectroscopy of Ca10(Ir4As8)(Fe2_xIrxAs2)5 shows that the Fe 3d electrons in the FeAs layer form the hole-like Fermi pocket at the zone center and the…
