Accepted: 22 March 1996
We develop the model of the short-range–order state for itinerant antiferromagnets with spin-density wave (SDW). The electronic spectrum, SDW amplitude and dynamical susceptibility are calculated. The existence of a fully diffusive magnetic mode at small wave vectors is predicted.
