摘要：

Using helical boundary conditions, we present exact-diagonalization results for two-dimensional spin-1/2 antiferromagnetic Heisenberg systems. Energy and staggered magnetization for an infinite system are obtained by extrapolation from finite square systems. Comparisons with the results obtained for periodic boundary conditions are made.
