Thermal Conductivity due to Spinons in the One-Dimensional Quantum Spin System Sr2V3O9
Takayuki Kawamata, Masanori Uesaka, Mitsuhide Sato +4
We have measured the thermal conductivity along different directions of the S = 1/2 one-dimensional (1D) spin system Sr2V3O9 in magnetic fields up to 14 T. It has been found that t…
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_…
Thermal Conductivity of the Quasi One-Dimensional Spin System Sr_2_V_3_O_9_
M. Uesaka, T. Kawamata, N. Kaneko +4
We have measured the thermal conductivity along the [101] direction, kappa_[101]_, along the [10-1] direction, kappa_[10-1]_, and along the b-axis, kappa_b_, of the quasi one-dimen…
Thermal Conductivity in the Bose-Einstein Condensed State of Triplons in the Bond-Alternating Spin-Chain System Pb2V3O9
Mitsuhide Sato, Takayuki Kawamata, Naoki Sugawara +5
In order to clarify the origin of the enhancement of the thermal conductivity in the Bose-Einstein Condensed (BEC) state of field-induced triplons, we have measured the thermal con…
