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…
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.…
Charge excitations associated with charge stripe order in the 214-type nickelate and superconducting cuprate
S. Wakimoto, H. Kimura, K. Ishii +10
Charge excitations were studied for stipe-ordered 214 compounds, LaSrNiO and 1/8-doped La(Ba, Sr)CuO using resonant inelastic x-ray scatteri…
Momentum-resolved charge excitations in high-Tc cuprates studied by resonant inelastic x-ray scattering
K. Ishii, M. Hoesch, T. Inami +14
We report a Cu K-edge resonant inelastic x-ray scattering (RIXS) study of high-Tc cuprates. Momentum-resolved charge excitations in the CuO2 plane are examined from parent Mott ins…
