摘要：
Within the Tyablikov's theoretical framework, the ground-state property of the two-dimensional antiferromagnetic Heisenberg model on a triangular lattice is studied. Our results show that the sublattice magnetization is M = 0.241 and the ground-state energy per bond is E-g/NZJ = -0.166, which are in agreement with the numerical simulations.
