摘要：

We show existence of Neel order for the ground state of a system with Ri two-dimensional layers with spin 1/2 and Heisenberg antiferromagnetic coupling, provided M greater than or equal to 8. The method uses the infrared bounds for the ground state combined with ideas introduced by Kennedy, Lieb, and Shastry.
