• Samples of the system SrCo_<1-x>Fe_xO_<3-y> (0<^-x<^-0,1<^-y<^-0.5) have been prepared under varying oxygen pressure and temperature and their crystal-lographic and magnetic properties have been studied. SrCoO_<2.5> with brown-millerite type structure (high temperature phase) is an antiferromagnet with the Neel temperature of 570K and the Co^<3+>-O_<2->-Co_<3+> superexchange interaction is strongly antiferromagnetic. SrCoO_3 and SrCo_<1-x>Fe_xO_3(x<0.9) with the cubic perovskite structure (high temperature phase) are ferromagnetic with the Curie temperature at about 200K and the magnetization decreases rapidly with increasing x near SrFeO_3 whose magnetic structure is helical.
