Concepts [1-4] are developed on these structures for A-B alloys having antiferromagnetic interaction between the individual local magnetic moments μ. The following cases are considered: 1) the exchange integrals IAA > 0, IBB < 0, IAB > 0, while μA and μB are dependent on the composition; 2) IAA > 0, IBB < 0, IAB < 0; μA, μB = const. Models are used to calculate the mean atomic magnetic moment for Co-Cr, Co-Mn, and Ni-Cr alloys. The agreement with experiment is satisfactory.
