Исследовано влияние синтеза под высоким давлением на магнитные  свойства семейства 314 кобальтитов Sr0,8Eu0,2Co1–xZnxO3–d  (x = 0; 0,05).  Наблюдаемое магнитное поведение обусловлено увеличением содержания кислорода, что приводит к образованию значительного        количества ионов Co4+. Как следствие, происходит усиление ферромагнитного состояния из-за возникновения сверхобменных взаимодействий Co4+–O–Co3+ и/или появление суперпарамагнитных кластеров ниже TC, связанных с переносом электронов между IS Co3+        и LS  Co4+. Полученные результаты  подчеркивают роль стехиометрии         кислорода в формировании магнитных свойств перовскитоподобных кобальтитов.

The present study investigates the impact of high-pressure synthesis on the magnetic properties of 314-related Sr0.8Eu0.2Co1–xZnxO3–d (x = 0; 0.05) cobaltites. The observed magnetic behavior is driven by an increase in oxygen content, leading to the formation of a significant number of Co4+ ions. This results in enhanced ferromagnetic interactions through Co4+–O–Co3+ exchange and/or the emergence of superparamagnetic clusters below TC, attributed to electron transfer between IS Co3+ and LS Co4+. These findings highlight the role of oxygen stoichiometry in tuning the magnetic properties of perovskite-related cobaltites.
