When the exchange potential in a ferromagnet is sufficiently large compared to the pair potential in a superconductor, an ensemble average of Josephson current is much smaller than its mesoscopic fluctuations. The Josephson current vanishes when the exchange potential is extremely large so that a ferromagnet is half-metallic. Spin-flip scattering at junction interfaces drastically changes the characteristic behavior of Josephson current. In addition to spin-singlet Cooper pairs, equal-spin triplet pairs penetrate into a half metal. Such equal-spin pairs have an unusual symmetry property called odd-frequency symmetry and carry the Josephson current through a half metal. The penetration of odd-frequency pairs into a half metal enhances the low energy quasiparticle density of states, which could be detected experimentally by scanning tunneling spectroscopy. We will also show that odd-frequency pairs in a half metal cause a nonmonotonic temperature dependence of the critical Josephson current.", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/11285"}]}, "item_10_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "American Physical Society"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://dx.doi.org/10.1103/PhysRevB.76.224525", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "American Physical Society, All rights reserved."}]}, "item_10_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_10_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1098-0121", "subitem_source_identifier_type": "ISSN"}]}, "item_10_text_14": {"attribute_name": "\u30d5\u30a9\u30fc\u30de\u30c3\u30c8", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Asano, Yasuhiro"}], "nameIdentifiers": [{"nameIdentifier": "27066", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sawa, Yuki"}], "nameIdentifiers": [{"nameIdentifier": "27067", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tanaka, Yukio"}], "nameIdentifiers": [{"nameIdentifier": "27068", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Golubov, Alexander A."}], "nameIdentifiers": [{"nameIdentifier": "27069", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "PhysRevB_76_224525.pdf", "filesize": [{"value": "668.8 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 668800.0, "url": {"label": "PhysRevB_76_224525.pdf", "url": "https://nagoya.repo.nii.ac.jp/record/9503/files/PhysRevB_76_224525.pdf"}, "version_id": "041e937b-49a5-45a0-8c73-79c58ed696f4"}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "Cooper pairs", "subitem_subject_scheme": "Other"}, {"subitem_subject": "critical current density (superconductivity)", "subitem_subject_scheme": "Other"}, {"subitem_subject": "electronic density of states", "subitem_subject_scheme": "Other"}, {"subitem_subject": "exchange interactions (electron)", "subitem_subject_scheme": "Other"}, {"subitem_subject": "ferromagnetic materials", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Green\u0027s function methods", "subitem_subject_scheme": "Other"}, {"subitem_subject": "interface states", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Josephson effect", "subitem_subject_scheme": "Other"}, {"subitem_subject": "magnetic superconductors", "subitem_subject_scheme": "Other"}, {"subitem_subject": "mesoscopic systems", "subitem_subject_scheme": "Other"}, {"subitem_subject": "quasiparticles", "subitem_subject_scheme": "Other"}, {"subitem_subject": "scanning tunnelling microscopy", "subitem_subject_scheme": "Other"}, {"subitem_subject": "spin fluctuations", "subitem_subject_scheme": "Other"}, {"subitem_subject": "triplet state", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Odd-frequency pairs and Josephson current through a strong ferromagnet", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Odd-frequency pairs and Josephson current through a strong ferromagnet"}]}, "item_type_id": "10", "owner": "1", "path": ["320/321/322"], "permalink_uri": "http://hdl.handle.net/2237/11285", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_name_i18n": "\u516c\u958b\u65e5", "attribute_value": "2009-03-10"}, "publish_date": "2009-03-10", "publish_status": "0", "recid": "9503", "relation": {}, "relation_version_is_last": true, "title": ["Odd-frequency pairs and Josephson current through a strong ferromagnet"], "weko_shared_id": 3}
