The results shows that the Bi-2212 grains with their c-axis parallel to the magnetic field were formed after the partial-melting and solidification in 8 T magnetic field, and transformed into the Bi-2223 grains with c-axis alignment during the further sintering process at 840℃ without magnetic field. The conversion of Bi-2212 grains to Bi-2223 grains has the heredity in grain alignment. The mixed structures of the Bi-2223 and the Bi-2212 grains with their c-axis parallel to the magnetic field are formed in samples sintered at 850℃-855℃ in 10 T magnetic field. Below 845℃ sintering in 10 T, a high proportion of Bi-2223 phase is obtained, however no preferred orientation is observed. The Bi-2223 grains with their c-axis parallel to the axial direction of the vertical tube furnace are formed not only on the surface, but also in the center of the sample sintered at 850℃ for 120 h in a 15℃/cm temperature gradient without magnetic field. Moreover, the samples sintered in the temperature gradient and in a 10 T magnetic field have a stronger c-axis alignment of Bi-2223 phase.\n強磁場で育成したBi系超伝導体の組織および超伝導特性について総合的に研究した。その結果、８Tの強磁場中における半溶融・凝固した試料の水平面では磁場付加方向にｃ軸配向するBi-2212 相の組織を確認することができる。さらに、無磁場840℃で焼結すると、水平面のｃ軸配向したBi-2212相はｃ軸配向したBi-2223相になる。Bi-2212相からBi-2223相への相変態では、Bi-2212相が配向していれば、その後の相変態によって生成するBi-2223相もｃ軸配向する。10Tの強磁場における850℃～855℃温度範囲で焼結した試料ではｃ軸配向したBi-2212相とBi-2223相の混合組織が観察された。10Tで845℃以下の温度で焼結した試料では、Bi-2223相の生成率が高いが、ｃ軸配向性はなかった。無磁場で15℃/cmの温度勾配下で焼結した試料ではｃ軸配向したBi-2223相の組織を示した。さらに、10Tの強磁場を印加した場合には、Bi-2223相の配向度が高くなることが分かった。","subitem_description_type":"Other"}]},"item_10002_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"秋田大学大学院工学資源学研究科"}]},"item_10002_source_id_27":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"21861382","subitem_source_identifier_type":"ISSN"}]},"item_10002_source_id_35":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA12500403","subitem_source_identifier_type":"NCID"}]},"item_10002_version_type_37":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"LU, Xiaoye"}],"nameIdentifiers":[{"nameIdentifier":"8986","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"魯, 小葉","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"8987","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-16"}],"displaytype":"detail","filename":"kougaku35(11).pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kougaku35(11).pdf","url":"https://air.repo.nii.ac.jp/record/2398/files/kougaku35(11).pdf"},"version_id":"99c48a71-fd22-4489-85c9-b60d6f763a93"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Bi-based Superconductors Fabricated in High Magnetic Fields","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Bi-based Superconductors Fabricated in High Magnetic Fields"}]},"item_type_id":"10002","owner":"3","path":["1046"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-01-08"},"publish_date":"2015-01-08","publish_status":"0","recid":"2398","relation_version_is_last":true,"title":["Bi-based Superconductors Fabricated in High Magnetic Fields"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-25T11:16:27.620364+00:00"}
