Valence-fluctuations combined with SOI bring an effective magnetic anisotropy driven by kinetic energy in the hybridization of delocalized 4f-electrons and conduction electrons. This kinetic-energy-driven anisotropy has an order of magnitude stronger energy scale than the magnetic anisotropy driven by potential energy of well localized 4f-electrons in the crystal fields. The relatively strong coupling between 4f-3d electrons make such kinetic-energy driven anisotropy robust against high temperatures. This mechanism of intrinsic magnetic anisotropy is not only scientifically intriguing but also promising for application to permanent magnets.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"International Conference on Strongly Correlated Electron Systems (SCES 2020/21)","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hiroaki, Shishido"}],"nameIdentifiers":[{"nameIdentifier":"1006236","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tetsuro, Ueno"}],"nameIdentifiers":[{"nameIdentifier":"1006237","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kotaro, Saito"}],"nameIdentifiers":[{"nameIdentifier":"1006238","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Masahiro, Sawada"}],"nameIdentifiers":[{"nameIdentifier":"1006239","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Munehisa, Matsumoto"}],"nameIdentifiers":[{"nameIdentifier":"1006240","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tetsuro, Ueno","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1006241","nameIdentifierScheme":"WEKO"}]}]},"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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Intrinsic coercivity induced by valence fluctuations in Ce(Co1-xCux)5 permanent magnet","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Intrinsic coercivity induced by valence fluctuations in Ce(Co1-xCux)5 permanent magnet"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-10-04"},"publish_date":"2021-10-04","publish_status":"0","recid":"83510","relation_version_is_last":true,"title":["Intrinsic coercivity induced by valence fluctuations in Ce(Co1-xCux)5 permanent magnet"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:21:04.415025+00:00"}
