Résumé en anglais

CaCuxMn7 – xO12 (x = 0, 0.15, 3) manganites were studied by 57Fe and 119Sn probe Mössbauer spectroscopy. It was established that the 57Fe and 119Sn probe cations are stabilized in the octahedral positions of the manganite structures by substituting the manganese cations. The magnetic and structure phase transition temperatures of CaMn7O12 and CaCu0.15Mn6.85O12 manganites fell upon the introduction of 57Fe probe cations into their structures. It was concluded that intrasublattice Mn4+–O–Mn4+ exchange interactions play a noticeable role in the formation of the magnetic structure of CaCu3Mn4O12 manganite.< Réduire
