Abstract

The spin wave theory with both kinematical and dynamical interactions for a cubic antiferromagnet is formulated. The kinematical interaction is shown to yield at low temperatures only exponentially small contributions to the partition function. The same is true for the dynamical interaction except for a series of diagrams yielding corrections to the ground state energy.
