The field dependence of the critical current density (Jc) is analyzed through the strong pinning model, with which the pristine sample is consistent. After the irradiation, the Jc aberrates from the strong pinning field dependence of B−5/8 and evolves to a weaker B−1/3\n dependence with an anomalous two-step behavior creating a cusplike feature. The cusp coincides with the field of the local minima in the normalized relaxation rate (S), manifested by increased pinning due to increased intervortex interactions followed by fast vortex dynamics caused by flux activation at higher fields. Furthermore, single vortex imaging reveals that while long-range triangular correlation of the Abrikosov vortex lattice is observed in pristine samples, irradiated samples exhibit a highly disordered glassy vortex state which is more densely packed with increased pinning force. These artificial defects incorporated via proton irradiation have the same pinning effect as Co doping which not only shifts the pinning force to a higher degree but also broadens its distribution, in contrast to P doping which only broadens the pinning distribution without inducing a shift. All in all, through this investigation, we provide a systematic understanding of the pinning behavior in \nBaFe2(As0.67P0.33)2\n through carefully controlling the defects in the system.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1103/PhysRevB.101.224507","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://journals.aps.org/prb/abstract/10.1103/PhysRevB.101.224507","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2469-9950","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":"Park, Akiyoshi"}],"nameIdentifiers":[{"nameIdentifier":"882014","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Veshchunov, Ivan"}],"nameIdentifiers":[{"nameIdentifier":"882015","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mine, Akinori"}],"nameIdentifiers":[{"nameIdentifier":"882016","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Pyon, Sunseng"}],"nameIdentifiers":[{"nameIdentifier":"882017","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tamegai, Tsuyoshi"}],"nameIdentifiers":[{"nameIdentifier":"882018","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitamura, Hisashi"}],"nameIdentifiers":[{"nameIdentifier":"882019","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitamura, Hisashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"882020","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":"Effects of 6 MeV proton irradiation on the vortex ensemble in  BaFe 2 ( As 0.67 P 0.33 ) 2  revealed through magnetization measurements and real-space vortex imaging","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effects of 6 MeV proton irradiation on the vortex ensemble in  BaFe 2 ( As 0.67 P 0.33 ) 2  revealed through magnetization measurements and real-space vortex imaging"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-08-04"},"publish_date":"2020-08-04","publish_status":"0","recid":"80286","relation_version_is_last":true,"title":["Effects of 6 MeV proton irradiation on the vortex ensemble in  BaFe 2 ( As 0.67 P 0.33 ) 2  revealed through magnetization measurements and real-space vortex imaging"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:39:26.923279+00:00"}
