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