A generalization of the s‐d–exchange model developed for domains in binary antiferromagnetic alloys is presented. It is shown that departures from the the ideal periodicity in the distribution of atoms among the lattice sites leads to a number of interaction processes between elementary excitations in the electron and spin sub‐systems which do not occur in ideal antiferromagnetics. In particular, electron‐magnon collisions arise which do not conserve quasi‐momentum. In the low temperature range these effects are dominant in the scattering of conduction electrons, giving rise, to a term proportional to T 2 in the electrical resistivity.
