The valence states of Fe and Co ions were estimated to be 3.56+ and 3.27+, respectively, which remained constant with changes in composition. Maximum oxygen desorption occurred at x = 0.2 below 800 °C. As temperature was increased and oxygen was released, a relationship was observed between the valence and coordination number changes of each B-site ion; these changes were more pronounced for the Fe ions than for the Co ions. In SrFe1−xCoxO3−δ samples, oxygen adjacent to Fe ions was released more readily than oxygen adjacent to Co ions. This conclusion is supported by the electronic states of the two B-site ions. These results are important for the design of new oxygen storage materials.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_11_publisher_31":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier","subitem_publisher_language":"en"}]},"item_11_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.jssc.2022.123254","subitem_relation_type_select":"DOI"}}]},"item_11_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2022 Elsevier Inc.
