Abstract : A magnetic study of perovskites REMn1-xBxO3 RE=Eu, Gd, Tb, Dy, Y ; B=Ni, Co is reported. It is found that investigated perovskites are nonhomogenous ferromagnets with relatively high Curie temperatures. The magnetic anisotropy of Ni-containing perovskites is much lower than that of Co-containing ones. It is supposed that domains with different charge state of ions and magnetic structure coexist in a wide range of Co- and Mn- concentrations. The metamagnetic behavior has been observed for REMn0.5Co0.5O3 perovskites RE=Gd,Tb,Dy ,Y.
