Abstract
Using an extension of the density matrix renormalization group method at finite temperature, we have calculated the magnetic susceptibility of the S = 1 antiferromagnetic Heisenberg chain with single-ion anisotropy. We investigate the dependence of the Haldane gap on the anisotropy energy. The results are compared with experimental data for the compound NENP.Keywords
