The Heisenberg antiferromagnet with both the nearest neighbor and the nextnearest neighbor interactions is studied in two and three dimensions. The spin waveexcitation spectrum is obtained based on the general four sublattice mean fieldground state in the region where the next nearest neighbor interactions prevail. It isshown that the continuous degeneracy of the mean field ground state is lifted by thezero-point spin wave fluctuations and the "strip" state with collinear spin ordering isstabilized.
