SYNTHESIS FEATURES AND DETERMINATION OF OXYGEN CONTENT IN DOUBLE PEROVSKITE-LIKE MANGANITES OF COMPOSITION LnBaMn2O6-Δ (LN = Nd, Sm)

The complex oxides were synthesized by precursor combustion in 3 steps. The oxygen content and the value of the oxygen capacity were determined by a conjunction of teragravim-etry with coulometric and iodometric titration methods. The ordered manganites were found to possess highest oxygen capacity.Работа выполнена при финансовой поддержке РНФ №19-79-10147
