Abstract
A magnetic study of perovskites RE(Mn1-xBx)O3 (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 RE(Mn0.5Co0.5)O3 perovskites (RE=Gd,Tb,Dy ,Y).
