Takayuki Kawamata, Nobuo Takahashi, Tadashi Adachi, Takashi Noji, Kazutaka Kudo, Norio Kobayashi, Yoji Koike

Journal of the Physical Society of Japan, 77(3) 034607-1-034607-6, Mar 10, 2008 Peer-reviewed

We have measured the thermal conductivity of the one-dimensional (1D) $S=1/2$ Heisenberg antiferromagnetic spin system of Sr2Cu1-xPdxO3 single crystals including nonmagnetic impurities of Pd2+. It has been found that the mean free path of spinons along the 1D spin chain at low temperatures is very close to the average length of finite spin chains between spin defects estimated from the magnetic susceptibility measurements. This proves that the thermal conduction due to spinons at low temperatures in Sr2CuO3 is ballistic as theoretically expected [Zotos et al.: Phys. Rev. Lett. 55 (1997) 11029].
