Observation of a dispersive charge mode in hole-doped cuprates using resonant inelastic x-ray scattering at the oxygen K edge
K. Ishii, T. Tohyama, S. Asano +13
We investigate electronic excitations in La2-x(Br,Sr)xCuO4 using resonant inelastic x-ray scattering (RIXS) at the oxygen K edge. RIXS spectra of the hole-doped cuprates show clear…
Bipartite magnetic parent phases in the iron-oxypnictide superconductor
Masatoshi Hiraishi, Soshi Iimura, Kenji M. Kojima +19
High-temperature (high-) superconductivity appears as a consequence of the carrier-doping of an undoped parent compound exhibiting antiferromagnetic order; thereby, grou…
Spin-orbit coupling induced semi-metallic state in the 1/3 hole doped hyper-kagome Na3Ir3O8
T. Takayama, A. Matsumoto, J. Nuss +5
The complex iridium oxide Na3Ir3O8 with a B-site ordered spinel structure was synthesized in single crystalline form, where the chiral hyper-kagome lattice of Ir atoms, as observed…
Resonant inelastic X-ray scattering study of intra-band charge excitations in hole-doped high-Tc cuprates
S. Wakimoto, K. Ishii, H. Kimura +10
We have performed resonant inelastic x-ray scattering (RIXS) near the Cu-K edge on cuprate superconductors La(2-x)Sr(x)CuO(4), La(2-x)Ba(x)CuO(4), La(2-x)Sr(x)Cu(1-y)Fe(y)O(4) and…
Resonant inelastic x-ray scattering in electronically quasi-zero-dimensional CuB2O4
J. N. Hancock, G. Chabot-Couture, Y. Li +6
We explore the general phenomenology of resonant inelastic scattering (RIXS) using CuB2O4, a network of CuO4 plaquettes electronically isolated by B+3 ions. Spectra show a small nu…
Momentum Dependence of Charge Excitations in the Electron-Doped Superconductor Nd1.85Ce0.15CuO4: a RIXS Study
K. Ishii, K. Tsutsui, Y. Endoh +9
We report a resonant inelastic x-ray scattering (RIXS) study of charge excitations in the electron-doped high-Tc superconductor Nd1.85Ce0.15CuO4. The intraband and interband excita…
