| dc.description.abstractEn | Anion-deficient substituted ferrites Ca2Fe2 − x N x O5 (N = Sc3+, Al3+) and mixed manganite CaMn7O12 have been investigated by 119Sn and 57Fe probe Mössbauer spectroscopy. The mechanism of charge compensation for heterovalent impurity Sn4+ ions in the structure of the ferrite Ca2Fe2O5 has been established. The presence of nonequivalent crystallographic positions of manganese cations, caused by their charge ordering in the structure of the manganite CaMn7O12, is shown. Magnetic ordering of Mn3+ and Mn4+ cations in the octahedral sublattice of CaMn7O12 at T < T M2 ≈ 90 K is established. | |
