摘要：

We report the results of quasi-elastic neutron scattering experiments on quasi one-dimensional antiferromagnets of hexagonal ABX3 type. In the S = 1 near-Heisenberg systems finite correlation lengths for T = 0 are extrapolated from the quasi one-dimensional temperature regime. This observation is in accordance with the Haldane conjecture for integer spin value systems, but the experimentally determined correlation lengths are larger than expected from the valence bond solid picture.
