JETP, 71 (1990) 1108), we calculate the phase diagram for degenerate antiferromagnetic semiconductors in the T-H plane for different current carrier densities. Both, wide-band semiconductors and 'double-exchange' materials, are investigated.5 pages, 6 figures, RevTex, Accepted for publication in PRBStrongly Correlated Electronstext
