Установлено, что твердые растворы (Pr, Nd, Sm)BaCoFeO5+δ характеризуются положительными отклонениями от идеальности, а их структурными параметрами, тепловыми и электротранспортными свойствами можно управлять путем направленного взаимозамещения РЗЭ в их структуре.</p></abstract><trans-abstract xml:lang="en"><p>Using the solid-state reaction method, (Pr,Nd,Sm)BaCoFeO5+δ solid solutions have been synthesized, their lattice constants and oxygen nonstoichiometry have been determined and their thermal expansion and electrical properties have been studied. It has been found that (Pr,Nd,Sm)BaCoFeO5+δ solid solutions show positive deviations from ideality and their structural parameters, thermal and electrotransport properties can be controlled by intersubstitution of rare earth elements in their structure.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Zhou Q., He T., He Q., J i Y. // Electrochem.
