摘要：

We obtained the eighth-order linked-cluster series for the free energy, the sublattice magnetization, and the staggered susceptibility of the spin-1/2 Heisenberg antiferromagnet on three-dimensional bipartite lattices. The series are analyzed using the standard extrapolation techniques with the application of a conformal transformation method to obtain the Neel temperature and the temperature dependence of sublattice magnetization. We obtain a more accurate estimate of the Neel temperature and the magnetic phase boundary for the body-centered cubic and the simple cubic lattices. The results are compared with related works.
