摘要：

Determinant representations of form factors are used to represent the spontaneous magnetization of the Heisenberg XXZ chain (Delta > 1) on the finite lattice as the ratio of two determinants. In the thermodynamic limit (the lattice of infinite length), the Baxter formula is reproduced in the framework of Algebraic Bethe Ansatz. It is shown that the finite size corrections to the Baxter formula are exponentially small. (C) 1999 Elsevier Science B.V. All rights reserved.
