摘要：

The static structure factors of the XXZ-model in the presence of a uniform field are determined from an exact computation of the ground states at given total spin on rings with N = 4, 6,..., 28 sites. Against the naive expectation, a weak uniform field strengthens the antiferromagnetic order in the transverse structure factor for the isotropic case.
