Post-growth annealing effects on charge and spin excitations in NdCeCuO
Kenji Ishii, Shun Asano, Masumi Ashida +6
We report a Cu K- and L-edge resonant inelastic x-ray scattering study of charge and spin excitations of bulk NdCeCuO, with focus on post-growth annealing effec…
Charge Excitations in NdCeCuO Observed with Resonant Inelastic X-ray Scattering: Comparison of Cu K-edge with Cu L-edge
Kenji Ishii, Masahito Kurooka, Yusuke Shimizu +3
We report a Cu K-edge resonant inelastic x-ray scattering (RIXS) study of momentum-dependent charge excitations in NdCeCuO ( = 0.075 and 0.18). The peak position…
Unusual coexistence of negative/positive charge-transfer in mixed-valence NaCaCrO
M. Taguchi, H. Yamaoka, Y. Yamamoto +6
We have investigated the electronic structure of NaCaCrO using x-ray absorption spectroscopy together with Anderson impurity model calculations with full multip…
Origin of Pressure-induced Superconducting Phase in KFeSe studied by Synchrotron X-ray Diffraction and Spectroscopy
Yoshiya Yamamoto, Hitoshi Yamaoka, Masashi Tanaka +12
Pressure dependence of the electronic and crystal structures of KFeSe, which has pressure-induced two superconducting domes of SC I and SC II, was investigated…
Anomalous metallic state in the vicinity of Metal to Valence Bond Solid insulator transition in LiVS2
N. Katayama, M. Uchida, D. Hashizume +9
We investigate LiVS2 and LiVSe2 with a triangular lattice as itinerant analogues of LiVO2, known for the formation of valence bond solid (VBS) state out of S = 1 frustrated magnet.…
Lattice Dynamics of LaFeAsO_{1-x}F_{x} and PrFeAsO_{1-y} via Inelastic X-Ray Scattering and First-Principles Calculation
T. Fukuda, A. Q. R. Baron, S. Shamoto +11
The lattice dynamics of LaFeAsO_{1-x}F_{x} (x=0, 0.1) and PrFeAsO_{1-y} (y~0.1) are investigated using inelastic x-ray scattering and ab-initio calculation. Measurements of powder…
