Результаты рентгеновской дифракции свидетельствуют о том, что с увеличением концентрации ионов Eu наблюдается структурный переход от ромбоэдрической (R3c) к неполярной орторомбической (Pnma) фазе через частичное образование антиполярной орторомбической структуры (Pbam). Смешанное фазовое состояние в полученных соединениях наблюдается в интервале 0,12 ≤ x ≤ 0,16. Магнитные измерения в сильном магнитном поле указывают на слабое ферромагнитное взаимодействие. Магнитный отклик в сильном поле объясняется расположением спинов на фазовой границе, а также наличием собственных антиферромагнитных спинов.</p></abstract><trans-abstract xml:lang="en"><p>The correlation between the multiphase state of the system and its magnetic properties was studied on Bi1–xEuxFeO3 ceramic samples in the range 0.12 ≤ x ≤ 0.18. The X-ray diffraction results indicate that, with an increase in the concentration of Eu ions, a structural transition from the rhombohedral (R3c) to nonpolar orthorhombic (Pnma) phase is observed through the partial formation of an antipolar orthorhombic structure (Pbam). The mixed phase state in the obtained compounds is observed in the range 0.12 ≤ x ≤ 0.16. Magnetic measurements in a strong magnetic field indicate a weak ferromagnetic interaction. The magnetic response in a strong field is explained by the location of the spins at the phase boundary, as well as by the presence of intrinsic antiferromagnetic spins.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мультиферроики</kwd><kwd>ионы-заместители</kwd><kwd>твердые растворы</kwd><kwd>рентгеновская дифракция</kwd><kwd>структурные фазовые переходы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>multiferroics</kwd><kwd>dopant ions</kwd><kwd>solid solutions</kwd><kwd>X-ray diffraction</kwd><kwd>structural phase transitions</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке БРФФИ (проект Ф21РМ-018) и РФФИ (проект 20-58- 04003Бел_мол_а)</funding-statement><funding-statement xml:lang="en">This work was supported by the BRFFR (project Ф21РМ-18) and RFFR (project 20-58- 04003Бел_мол_а)</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">Reversible phase transition induced large piezoelectric response in Sm-doped BiFeO3 with a composition near the morphotropic phase boundary / Z.
