Observation of spin-conserving two-spinon continuum in the =1/2 antiferromagnetic chain system SrCuO using Cu -edge resonant inelastic x-ray scattering
Kenji Ishii, Kenji Tsutsui, Takayuki Kawamata +1
We report a Cu -edge resonant inelastic x-ray scattering (RIXS) study of spin excitations in the =1/2 antiferromagnetic chain system SrCuO. The spectral weight observ…
Thermal Conductivity and Magnetic Phase Diagram of CuB2O4
T. Kawamata, N. Sugawara, S. M. Haidar +11
We have measured temperature and magnetic field dependences of the thermal conductivity along the c-axis, kc, and that along the [110] direction, k110, of CuB2O4 single crystals in…
Metal-Insulator Transition and Pseudogap in BiPbSrCuO High- Cuprates
M. Miyazaki, R. Kadono, M. Hiraishi +6
It is inferred from bulk-sensitive muon Knight shift measurement for a BiPbSrCuO single-layer cuprate that metal-insulator (MI) transition (in th…
Thermal Conductivity of the S = 1/2 Quasi-One-Dimensional Ferromagnetic Spin System CsCuCl3
T. Kawamata, H. Sudo, Y. Matsuoka +4
We have measured the thermal conductivity along the c-axis, \k{appa}||c, parallel to ferromagnetic spin-chains of single crystals of the S = 1/2 quasi-one-dimensional spin system C…
The Role of Lattice Coupling in Establishing Electronic and Magnetic Properties in Quasi-One-Dimensional Cuprates
W. S. Lee, S. Johnston, B. Moritz +11
High resolution resonant inelastic x-ray scattering has been performed to reveal the role of lattice-coupling in a family of quasi-1D insulating cuprates, CaYCu$_…
Enhancement of Thermal Conductivity due to Spinons in the One-Dimensional Spin System SrCuO_2
T. Kawamata, N. Kaneko, M. Uesaka +2
We have measured the thermal conductivity along the c-axis parallel to the spin-chains, kappa_c, of the one-dimensional antiferromagnetic spin system SrCuO_2, using as-grown and O_…
