The valence state of Co ions in $[(ca_{1-x}Y_x)_{2}CoO_{3}]_{0.62}CoO_{2}(0 leqq x leqq 0.04)$ has been clarified as $Co^{3.2+}$ in $CoO_{2}$ sheet and $Co^{3.6+}$ in RS-type BL, respectively. In addition,both a broad minimum at around 100K $(T_{SDW}^{on})$ and a broad maximum between $T_{SS}^{end}$ and $T_{SS}^{on}$ in the ρ(T) curve correspond to two magnetic transitions,where $T_{SS}^{end}$ and $T_{SS}^{on}$ could correspond to the spin-state transition of Co ions in the $CoO_{2}$ sheet and in the RS-type BL, respectively. Furthermore,in x= 0.02 and 0.04 samples,the seebeck coeddicient at 800K, show the highest value (S = 176μ V/K) .Therefore, Y doped $Ca_{3}Co_{4}O_{9}$ are potential candidates for the practical use of thermoelectric power generations.","subitem_description_type":"Abstract"}]},"item_2_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"ナカツガワ, ヒロシ"}]}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{}]}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IEEE"}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1109/ICT.2007.4569404","subitem_relation_type_select":"DOI"}}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"10942734 ","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Yokohama National University"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nakatsugawa, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"17422","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Jeong, H.
