摘要：
The nuclear spin-lattice relaxation rate (1/T-1) of Li-7 nuclei has been measured in a spin S=1/2 double-linear-chain system with exchange interaction J=308 K, gamma-LiV2O5, in the temperature range from 280 K down to 0.5 K. We observed that 1/T-1 shows the minimum at about 0.1 J. The increase of 1/T-1 below and above 0.1 J are well explained by considering the contribution from the staggered-spin fluctuation and the uniform-spin fluctuation, respectively. Especially, the increase of 1/T-1 below 0.1 J suggests the appearance of the logarithmic correction effect which has been recently predicted by theoretical works in an isotropic Heisenberg linear chain.
