摘要: Abstract We review the experimental results on a spin ( S ) one, one-dimensional Heisenberg antiferromagnet (1DHA). In particular, how has existence of Haldane gap been confirmed and what is nature ground state, are discussed. latter part this paper, our recent experiments = 2 1DHA 1D antiferromagnets with competing exchange interactions reported.
