In particular, the temperature and electric currents in a storage battery need to be monitored simultaneously with 1 kHz signal bandwidth for optimum battery usage. Here we introduce a centimeter-scale portable quantum sensor head, consisting of a diamond substrate hosting an ensemble of nitrogen-vacancy (NV) color centers with a density of 3 x 1017 cm3. One diamond surface is attached to a multi-mode fiber for simultaneous optical excitation and readout of the NV centers, while the other diamond surface is attached to a coplanar microwave guide for NV spin ground-state mixing. Signal bandwidth of 1 kHz was realized through time-domain multiplexing of the two-tone microwave frequency modulation at 20 kHz. Two microwave frequencies were locked to the two resonance points that were determined from the optically detected magnetic resonance spectrum. From the mean and the difference of the deviation from the two locked frequencies, the temperature and magnetic field were obtained simultaneously and independently, with sensitivities of 3.5 nT/Hz1/2 and 1.3 mK/Hz1/2, respectively. We also showed that our sensor reached a minimum detectable magnetic field of 5 pT by accumulating signals for over 10 000 s.", "subitem_description_type": "Abstract"}]}, "item_8_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "AIP Publishing"}]}, "item_8_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1063/5.0031502", "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://aip.scitation.org/doi/10.1063/5.0031502", "subitem_relation_type_select": "URI"}}]}, "item_8_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0003-6951", "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": "Hatano, Yuji"}], "nameIdentifiers": [{"nameIdentifier": "1012744", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Shin, Jaewon"}], "nameIdentifiers": [{"nameIdentifier": "1012745", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nishitani, Daisuke"}], "nameIdentifiers": [{"nameIdentifier": "1012746", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Iwatsuka, Haruki"}], "nameIdentifiers": [{"nameIdentifier": "1012747", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yuta, Masuyama"}], "nameIdentifiers": [{"nameIdentifier": "1012748", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sugiyama, Hiroki"}], "nameIdentifiers": [{"nameIdentifier": "1012749", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ishii, Makoto"}], "nameIdentifiers": [{"nameIdentifier": "1012750", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Shinobu, Onoda"}], "nameIdentifiers": [{"nameIdentifier": "1012751", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Takeshi, Ohshima"}], "nameIdentifiers": [{"nameIdentifier": "1012752", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Arai, Keigo"}], "nameIdentifiers": [{"nameIdentifier": "1012753", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Iwasaki, Takayuki"}], "nameIdentifiers": [{"nameIdentifier": "1012754", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Mutsuko, Hatano"}], "nameIdentifiers": [{"nameIdentifier": "1012755", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yuta, Masuyama", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "1012756", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Shinobu, Onoda", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "1012757", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Takeshi, Ohshima", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "1012758", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Mutsuko, Hatano", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "1012759", "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": "Simultaneous thermometry and magnetometry using a fiber-coupled quantum diamond sensor", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Simultaneous thermometry and magnetometry using a fiber-coupled quantum diamond sensor"}]}, "item_type_id": "8", "owner": "1", "path": ["1"], "permalink_uri": "https://repo.qst.go.jp/records/81922", "pubdate": {"attribute_name": "公開日", "attribute_value": "2021-02-16"}, "publish_date": "2021-02-16", "publish_status": "0", "recid": "81922", "relation": {}, "relation_version_is_last": true, "title": ["Simultaneous thermometry and magnetometry using a fiber-coupled quantum diamond sensor"], "weko_shared_id": -1}
