We report here the results of 51V-NMR experiments as well as susceptibility and high-filed magnetization measurements on a spin-1/2 honeycomb lattice antiferromagnet InCu2/3V1/3O3. The magnetization curve at 4.2 K showed no anomaly up to 54 T. A small anomaly around 38 K was found in the nuclear spin-latteice relaxation rate T -11 as well as the susceptibility, while NMR spectrum was temperature independent. Further, T-11 showed a broad maximum around 15 K and a tendency to be constant towards the lowest temperature of 2 K. Our results suggest that a large spin fluctuation remains until 2 K without a specific magnetic long-range ordering. Preliminary NMR results for an oriented sample are also shown.
