Bulk Spin Polarization of CoFeS
C. Utfeld, S. R. Giblin, J. W. Taylor +8
We report on a new method to determine the degree of bulk spin polarization in single crystal CoFeS by modeling magnetic Compton scattering with {\it ab initio} c…
Resonant inelastic x-ray scattering in single-crystal superconducting PrFeAsO0.7
I. Jarrige, K. Ishii, M. Yoshida +9
Resonant inelastic x-ray scattering (RIXS) spectra at the Fe K-edge were measured for a single crystal of the iron oxypnictide superconductor PrFeAsO0.7 (Tc=42 K). They disclose a…
Bulk electronic structure of optimally doped Ba(FeCo)As
C. Utfeld, J. Laverock, T. D. Haynes +10
We report high-resolution, bulk Compton scattering measurements unveiling the Fermi surface of an optimally-doped iron-arsenide superconductor, Ba(FeCo)As…
Direct observation of localization in the minority-spin-band electrons of magnetite below the Verwey temperature
H. Kobayashi, T. Nagao, M. Itou +5
Two-dimensional spin-uncompensated momentum density distributions, s, were reconstructed in magnetite at 12K and 300K from several measured directional mag…
Evidence for Oxygen Holes due to d-p Rehybridization in Thermoelectric Sr_{1-x}Rh_{2}O_{4}
Y. Ishida, T. Baba, R. Eguchi +8
Soft-x-ray photoemission and absorption spectroscopies are employed to investigate the electronic structures of Sr_{1-x}Rh_{2}O_{4}. Similarly to the layered cobaltates such as Na_…
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…
