摘要：

Temperature dependence of the correlation length of the one-dimensional S=2 Heisenberg antiferromagnet is investigated numerically, to compare with those of the S=1/2, 1, 3/2 models. The correlation length of the S=2 model is found to be saturated to a value xi-1 congruent-to 0.012(2) as T-->0, which confirms the Haldane conjecture. Combined with the estimate xi-1 congruent-to 0.16 of the S=1 model by other authors, the present estimate is well explained by xi-1 is similar to S exp (-piS).
