Fermi-liquid state in *-type LaEuSrCuO revealed via element substitution effects on magnetism
Takanori Taniguchi, Kota Kudo, Shun Asano +4
Despite its unique structural features, the magnetism of single-layered cuprate with five oxygen coordination (*-type structure) has not been investigated thus far. Here, we rep…
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…
Distinct variation of electronic states due to annealing in LaEuCuO and NdCuO
Shun Asano, Kenji Ishii, Daiju Matsumura +8
We performed Cu {\it K}-edge X-ray absorption fine structure measurements on T'-type LaEuCuO (LECO) and NdCuO (NCO) to investigate the variation in the…
Revisiting the phase diagram of T*-type LaEuSrCuO using Oxygen -edge X-ray absorption spectroscopy
Shun Asano, Kenji Ishii, Kohei Yamagami +3
Oxygen -edge X-ray absorption spectroscopy measurements were conducted on T*-type LaEuSrCuO (LESCO) to estimate the hole density () and in…
Oxidation annealing effects on the spin-glass-like magnetism and appearance of superconductivity in T*-type LaEuSrCuO (0.14 0.28)
Shun Asano, Kensuke M. Suzuki, Kota Kudo +9
We investigated the magnetism and superconductivity in as-sintered (AS) and oxidation annealed (OA) T*-type LaEuSrCuO (LESCO) with 0.14 0.…
Observation of two types of charge density wave orders in superconducting LaSrCuO
J. -J. Wen, H. Huang, S. -J. Lee +9
The discovery of charge- and spin-density-wave (CDW/SDW) orders in superconducting cuprates has altered our perspective on the nature of high-temperature superconductivity (SC). Ho…
Ce-doping and reduction annealing effects on electronic states in PrCeCuO studied by Cu -edge X-ray absorption spectroscopy
Shun Asano, Kenji Ishii, Daiju Matsumura +4
We investigated Ce-substitution and reduction annealing effects on the electronic states at copper sites by Cu -edge x-ray absorption near-edge structure measurements in Pr$_{…
Superconductivity-insensitive order at ~1/4 in electron doped cuprates
H. Jang, S. Asano, M. Fujita +5
One of the central questions in the cuprate research is the nature of the "normal state" which develops into high temperature superconductivity (HTSC). In the normal state of hole-…
