Abstract
The crystal structure and magnetic properties of orthomanganites R1-xMnO3+y (R=La, Eu ; x≤0.2 ; y ≤0.13) were investigated. It was shown that the increase of oxygen content leads to the transformation from the antiferromagnetic to the ferromagnetic state in these compounds. The Curie temperatures of La1-xMnO3+y and freezing temperatures of magnetic clusters for Eu1-xMnO3+y in the samples with deficit of A-cations are higher than those in parent compounds (with x=0). The magnetic data indicate that the mixed magnetic state involving ferro- and antiferromagnetic domains is realized in the intermediate range of x, y values.
