Abstract
A magnetic study of perovskites RE(Mn(1.x)Bx)O-3 (RE=Eu, Gd, Tb, Dy, Y ; B=Ni, Co) is reported, It is found that investigated perovskites are nonhomogenous ferromagnets witt relatively high Curie temperatures. T he magnetic anisotropy of Ni-containing perovskites is much lower than tl?at of Co-containing ones. It is supposed that domains with differe nt charge state of ions and magnetic structure coexist in a wide range of Co- and Mn- concentrations. The metamagnetic behavior has been obs erved For RE(Mn0.5Co0.5)O-3 perovskites (RE=Gd,Tb,Dy,Y).
