Changes in interatomic distances, absolute values of atomic displacements and their anisotropy were examined on those specimens with single-crystal X-ray diffractometry and successive structure refinements. As a result, not only an abrupt weakening of cation-anion bonds but also disappearance of a particular lattice vibration mode (dynamic) were observed on heteroatom-doped specimens. By comparing the reported atomic displacements (static) in the low temperature phase and the lattice mode which should be unique on the high temperature phase, the author confirmed that the atomic displacements in the low temperature phase is a “frozen” phonon which is unique in the high temperature, semimetallic phase of magnetite.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:16K05604, 研究期間(年度):2016-04-01 - 2019-03-31","subitem_description_type":"Other"},{"subitem_description":"出典：研究課題「遷移金属酸化物を用いた電子フォノン相互作用の実証的研究」課題番号16K05604\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-16K05604/16K05604seika/)を加工して作成","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00056647","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_17":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"金沢大学理工研究域地球社会基盤学系"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=50401881"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=50401881","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-16K05604/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-16K05604/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-16K05604/16K05604seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-16K05604/16K05604seika/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"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":"奥寺, 浩樹"}],"nameIdentifiers":[{"nameIdentifier":"80481","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"50401881","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=50401881"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-05-15"}],"displaytype":"detail","filename":"TE-PR-OKUDERA-H-kaken 2019-4p.pdf","filesize":[{"value":"110.7 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"TE-PR-OKUDERA-H-kaken 2019-4p.pdf ","url":"https://kanazawa-u.repo.nii.ac.jp/record/50338/files/TE-PR-OKUDERA-H-kaken 2019-4p.pdf"},"version_id":"71230a8e-23a8-4b23-a677-8a872f73d64e"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"遷移金属酸化物を用いた電子フォノン相互作用の実証的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"遷移金属酸化物を用いた電子フォノン相互作用の実証的研究"},{"subitem_title":"Empirical research of electron-phonon interaction on transition-metal oxides","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2815"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-05-15"},"publish_date":"2020-05-15","publish_status":"0","recid":"50338","relation_version_is_last":true,"title":["遷移金属酸化物を用いた電子フォノン相互作用の実証的研究"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-07-01T05:30:10.718147+00:00"}
