AbstractAbstract
[en] The effect of the interplane and intraplane anisotropies on the energy gap for odd number of coupled quantum spin-1/2 antiferromagnetic anisotropic Heisenberg planes is investigated using a linear spin wave theory. However, in the isotropic case, such system exhibits a long range order, and no energy gap, while in the anisotropic case, the energy gap opens above a critical anisotropic value. The known results of a single plane have been obtained. (author)
