The previous termcritical currentnext term density increased by these treatments over a wide range of magnetic fields. It is proposed that the improvement of the previous termcritical currentnext term density at low magnetic fields comes from the reduction of the grain size in the specimen sintered at low temperatures and from the increase in the elementary pinning force of grain boundaries in the C-doped specimens. On the other hand, the improvement of the previous termcritical currentnext term density at high fields is mainly caused by the enhancement of the upper previous termcriticalnext term field due to the electron scattering by grain boundaries and C atoms.","subitem_description_type":"Abstract"}]},"item_21_description_60":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Journal Article","subitem_description_type":"Other"}]},"item_21_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"affiliations":[{"affiliationNames":[{"affiliationName":"","lang":"ja"}],"nameIdentifiers":[]}],"familyNames":[{"familyName":"小田部","familyNameLang":"ja"},{"familyName":"オタベ","familyNameLang":"ja-Kana"},{"familyName":"Otabe","familyNameLang":"en"}],"givenNames":[{"givenName":"エドモンド 荘司","givenNameLang":"ja"},{"givenName":"エドモンド ソウジ","givenNameLang":"ja-Kana"},{"givenName":"Edmund Soji","givenNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"572","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"30231236","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000030231236"},{"nameIdentifier":"7003400054","nameIdentifierScheme":"Scopus著者ID","nameIdentifierURI":"https://www.scopus.com/authid/detail.uri?authorId=7003400054"},{"nameIdentifier":"0000-0001-9880-8240","nameIdentifierScheme":"ORCiD","nameIdentifierURI":"https://orcid.org/0000-0001-9880-8240"},{"nameIdentifier":"205","nameIdentifierScheme":"九工大研究者情報","nameIdentifierURI":"https://hyokadb02.jimu.kyutech.ac.jp/html/205_ja.html"}],"names":[{"name":"小田部, エドモンド 荘司","nameLang":"ja"},{"name":"オタベ, エドモンド ソウジ","nameLang":"ja-Kana"},{"name":"Otabe, Edmund Soji","nameLang":"en"}]}]},"item_21_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_21_relation_12":{"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.physc.2006.04.039","subitem_relation_type_select":"DOI"}}]},"item_21_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © 2006 Elsevier B.V.
