Here we show that nuclear-spin assisted quantum tunnelling can also control the dynamics of purely emergent excitations: magnetic monopoles in spin ice. Our low temperature experiments were conducted on canonical spin ice materials with a broad range of nuclear spin values. By measuring the magnetic relaxation, or monopole current, we demonstrate strong evidence that dynamical coupling with the hyperfine fields bring the electronic spins associated with magnetic monopoles to resonance, allowing the monopoles to hop and transport magnetic charge. Our result shows how the coupling of electronic spins with nuclear spins may be used to control the monopole current. It broadens the relevance of the assisted quantum tunnelling mechanism from single molecular spins to emergent excitations in a strongly correlated system.","subitem_description_type":"Abstract"}]},"item_21_description_60":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Journal Article","subitem_description_type":"Other"}]},"item_21_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Nature Publishing Group"}]},"item_21_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1038/s41467-019-09323-6","subitem_relation_type_select":"DOI"}}]},"item_21_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (c) The Author(s) 2019"},{"subitem_rights":"Creative Commons Attribution 4.0 International License"},{"subitem_rights":"http://creativecommons.org/licenses/by/4.0/"}]},"item_21_select_59":{"attribute_name":"査読の有無","attribute_value_mlt":[{"subitem_select_item":"yes"}]},"item_21_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2041-1723","subitem_source_identifier_type":"ISSN"}]},"item_21_subject_16":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"427","subitem_subject_scheme":"NDC"}]},"item_21_text_36":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Institut Néel, C.N.R.S—Université Grenoble Alpes, BP 166, 38042 Grenoble, France."},{"subitem_text_value":"School of Physics and Astronomy, Cardiff University, Cardiff CF24 3AA, UK."},{"subitem_text_value":"Institut Néel, C.N.R.S—Université Grenoble Alpes, BP 166, 38042 Grenoble, France."},{"subitem_text_value":"Clarendon Laboratory, Physics Department, Oxford University, Oxford OX1~3PU, UK."},{"subitem_text_value":"Kyushu Institute of Technology, Kitakyushu 804-8550, Japan."},{"subitem_text_value":"Department of Physics, University of Warwick, Coventry CV4 7AL, UK."},{"subitem_text_value":"London Centre for Nanotechnology and Department of Physics and Astronomy, University College London, 17-19 Gordon Street, London WC1H 0AJ, UK."}]},"item_21_text_63":{"attribute_name":"連携ID","attribute_value_mlt":[{"subitem_text_value":"7812"}]},"item_21_version_type_58":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Paulsen,  C."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Giblin,  S.R."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Lhotel,  E."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Prabhakaran,  D."}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"Matsuhira, Kazuyuki","creatorNameLang":"en"},{"creatorName":"松平, 和之","creatorNameLang":"ja"},{"creatorName":"マツヒラ, カズユキ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{},{},{},{},{}]},{"creatorNames":[{"creatorName":"Balakrishnan,  G."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Bramwell,  S.T."}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-19"}],"displaytype":"detail","filename":"scunit-2019_05.pdf","filesize":[{"value":"2.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"scunit-2019_05.pdf","url":"https://kyutech.repo.nii.ac.jp/record/6087/files/scunit-2019_05.pdf"},"version_id":"47352e3b-5b4a-407a-b38d-002ec6a050e3"}]},"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":"Nuclear spin assisted quantum tunnelling of magnetic monopoles in spin ice","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Nuclear spin assisted quantum tunnelling of magnetic monopoles in spin ice"}]},"item_type_id":"21","owner":"3","path":["9"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-07-19"},"publish_date":"2019-07-19","publish_status":"0","recid":"6087","relation_version_is_last":true,"title":["Nuclear spin assisted quantum tunnelling of magnetic monopoles in spin ice"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2024-04-02T08:40:18.072064+00:00"}
