Glassy Spin Freezing and Gapless Spin Dynamics in a Spatially Anisotropic Triangular Antiferromagnet Ag2MnO2
S. Ji, J. -H. Kim, Y. Qiu +6
Using elastic and inelastic neutron scattering techniques, we show that upon cooling a spatially anisotropic triangular antiferromagnet AgMnO freezes below K…
Longitudinal SDW order in a quasi-1D Ising-like quantum antiferromagnet
S. Kimura, M. Matsuda, T. Masuda +10
From neutron diffraction measurements on a quasi-1D Ising-like Co spin compound BaCoVO, we observed an appearance of a novel type of incomm…
Magnetic Excitations of the Diagonal Incommensurate Phase in Lightly-Doped La2-xSrxCuO4
M. Matsuda, M. Fujita, S. Wakimoto +3
We present inelastic neutron scattering experiments on a single-domain crystal of lightly-doped La1.96Sr0.04CuO4. We find that the magnetic excitation spectrum in this insulating p…
Doping Dependence of Low-energy Spin Fluctuations in Electron-Doped Cuprates PrLaCeCuO
M. Fujita, M. Matsuda, S. -H. Lee +2
The low-energy spin fluctuations in the electron-doped PrLaCeCuO have been investigated over a wide concentration range of 0.07 0.18 t…
Effects of hole-doping on the magnetic ground state and excitations in the edge-sharing CuO chains of CaYCuO
M. Matsuda, K. Kakurai, S. Kurogi +5
Neutron scattering experiments were performed on the undoped and hole-doped CaYCuO, which consists of ferromagnetic edge-sharing CuO chains. It was p…
Magnetic field effects and magnetic anisotropy in lightly doped La_{2-x}Sr_xCuO_4
M. Matsuda, M. Fujita, K. Yamada +3
The effects of the application of a magnetic field on the diagonal stripe spin-glass phase is studied in lightly doped La_{2-x}Sr_xCuO_4 (x=0.014 and 0.024). With increasing magnet…
