Показано, что образец является структурно двухфазным. Основная фаза имеет тетрагонально искаженную элементарную ячейку и описывается пространственной группой I4/ттт. Уширение рефлексов с индексами, соответствующими удвоению параметра с элементарной ячейки, указывает на отсутствие строгой трансляционной симметрии вдоль оси с. Наличие уширенного сверхструктурного рефлекса, наблюдаемого на малых углах на рентгенограммах при температуре меньше 400 К, обусловлено моноклинной фазой, содержание которой значительно меньше, чем тетрагональной. Спонтанная намагниченность появляется при формировании моноклинной фазы. Магнитная структура является преимущественно антиферромагнитной структурой G-типа с магнитными моментами 1,5µB в слоях из октаэдров СоO6 и 2µB в анион-дефицитных СоO4+γ слоях. Электропроводность состава Sr0,9Y0,1CoO2,63 имеет полупроводниковый характер. Магнитосопротивление достигает 57 % в поле 14 Тл при температуре 5 К и значительно уменьшается с ростом температуры.</p></abstract><trans-abstract xml:lang="en"><p>The structure, magnetic and magnetotransport properties of perovskite Sr0.9Y0.1CoO2.63 are studied. It is shown that the sample is structurally two-phase. The main phase has a tetragonal-distorted unit cell and is described by the spatial group I4/mmm. The broadening of the reflexes with indexes corresponding to a doubling of the parameter from the unit cell indicates that there is no strict translational symmetry along the с-axis. The presence of a broadened superstructural reflex observed at small angles on X-ray diffraction patterns at temperatures below 400 K is due to the monoclinic phase, whose content is much smaller than the tetragonal phase. Spontaneous magnetization appears during the formation of the monoclinic phase. The magnetic structure is predominantly an antiferromagnetic G-type structure with magnetic moments of 1.5µB in the layers of CoO6 octahedra and 2µB in the anion-deficient CoO4+γ layers. The electrical conductivity of Sr0.9Y0.1CoO2.63 has a semiconductor in character. The magnetoresistance reaches 57 % in a field of 14 T at a temperature of 5 K and decreases strongly with increasing temperature.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>магнитные материалы</kwd><kwd>фазовые превращения</kwd><kwd>обменное взаимодействие</kwd></kwd-group><kwd-group xml:lang="en"><kwd>magnetic materials</kwd><kwd>phase transitions</kwd><kwd>exchange interactions</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Белорусский республиканский фонд фундаментальных исследований, проект Ф17Д-007</funding-statement><funding-statement xml:lang="en">Belarusian Republican Foundation for Fundamental Research, Grant Ф17Д-007</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Особенности спинового, зарядового и орбитального упорядочений в кобальтитах / Н.
