We utilize the irreversible magnetization and its relaxation to evaluate the screening current density and vortex dynamics before and after the introduction of point defects created by 3-MeV proton (H+) irradiation with a dose of  5.8×10 16H+cm2. In the as-grown crystal, both J and vortex dynamics are strongly influenced by temperature and magnetic field, indicating that the predominant pinning is not the weak-collective pinning but the strong pinning. With an introduction of point defects, J in the H+-irradiated crystal at 2 K reaches 1.1×10 7 cm−2, which is one of the largest values in iron-based superconductors. In contrast to the as-grown sample, the sensitivity to the temperature and magnetic field becomes quite mild, and the vortex system is described by a simple weak-collective pinning scenario.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IOP Publishing Ltd"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1088/0953-2048/28/8/085003","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://iopscience.iop.org/0953-2048/28/8/085003"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://iopscience.iop.org/0953-2048/28/8/085003","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0953-2048","subitem_source_identifier_type":"ISSN"}]},"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":"Taen, Toshihiro"}],"nameIdentifiers":[{"nameIdentifier":"474591","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohtake, Fumiaki"}],"nameIdentifiers":[{"nameIdentifier":"474592","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Pyon, Sunseng"}],"nameIdentifiers":[{"nameIdentifier":"474593","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tamegai, Tsuyoshi"}],"nameIdentifiers":[{"nameIdentifier":"474594","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitamura, Hisashi"}],"nameIdentifiers":[{"nameIdentifier":"474595","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田縁 俊光","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"474596","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大竹 史哲","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"474597","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"卞 舜生","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"474598","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"為ケ井 強","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"474599","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"北村 尚","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"474600","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Critical current density and vortex dynamics in pristine and proton-irradiated Ba0.6K0.4Fe2As2","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Critical current density and vortex dynamics in pristine and proton-irradiated Ba0.6K0.4Fe2As2"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-05-18"},"publish_date":"2016-05-18","publish_status":"0","recid":"47400","relation_version_is_last":true,"title":["Critical current density and vortex dynamics in pristine and proton-irradiated Ba0.6K0.4Fe2As2"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:40:18.549816+00:00"}
