Abstract
In this paper we study the effect of next-nearest-neighbor exchange on antiferromagnetic order and spin correlation of quasi-two-dimensional antiferromagnets in terms of our anisotropic nonlinear spin wave theo ry. We emphasize the Neel temperature, antiferromagnetic order paramet er, and spin correlation as functions of the next-nearest-neighbor exc hange parameter. We apply the theoretical results to the antiferromagn etic properties of insulating cuprates.
