Incommensurate Antiferromagnetic Order in the Fe-substituted Bi-2201 Cuprate in the Heavily Overdoped Regime

Y. Komiyama, Y. Ikeda, T. Taniguchi +10

Elastic neutron scattering experiments showed incommensurate antiferromagnetic peaks in 5% Fe-substituted Bi-2201 cuprate in the non-superconducting heavily overdoped regime. The i…

Observation of spin-conserving two-spinon continuum in the $S$ =1/2 antiferromagnetic chain system Sr $_{2}$ CuO $_{3}$ using Cu $K$ -edge resonant inelastic x-ray scattering

Kenji Ishii, Kenji Tsutsui, Takayuki Kawamata +1

We report a Cu $K$ -edge resonant inelastic x-ray scattering (RIXS) study of spin excitations in the $S$ =1/2 antiferromagnetic chain system Sr $_{2}$ CuO $_{3}$ . The spectral weight observ…

Electronic State of T'-Pr $_{1.3 - x}$ La $_{0.7}$ Ce $_{x}$ CuO $_{4}$ ( $x = 0.10$ ) Studied by Compton Scattering

Takayuki Kawamata, Shin Saito, Naruki Tsuji +5

We have performed Compton scattering measurements on as-grown and reduced single crystals of the electron-doped T'-cuprate Pr1.3-xLa0.7CexCuO4 (x = 0.10) to investigate the effect…

Estimation of the on-site Coulomb potential 1 and covalent state in La2CuO4 by muon spin rotation 2 and density functional theory calculations

Muhammad Redo Ramadhan, Budi Adiperdana, Irwan Ramli +12

The on-site Coulomb potential, U, and the covalent state of electronic orbitals play key roles for the Cooper pair symmetry and exotic electromagnetic properties of high-Tc superco…

Magnetism of Kitaev spin-liquid candidate material RuBr $_{3}$

Yoshinori Imai, Kazuhiro Nawa, Yasuhiro Shimizu +16

The ruthenium halide $α$ -RuCl $_{3}$ is a promising candidate for a Kitaev spin liquid. However, the microscopic model describing $α$ -RuCl $_{3}$ is still debated partly because of a…
