Microwave irradiation with a high and\nhomogeneous power density into a large detection volume is necessary to realize a highly sensitive magnetometer. In this study, we fabricate a microwave resonator to enhance the power density of the microwave field and an optical system. By the strong microwave field, 48 ns Rabi oscillation which is sufficiently faster than the phase relaxation time of NV centers is realized. In addition, combining with a decoupling pulse sequence (XY16), the spin coherence time (T2) extends to 27 times longer than that with a spin echo method. Consequently, we obtained an AC magnetic field sensitivity of 10.8 pt/\npHz using the dynamical decoupling pulse sequence.","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":"10.1063/1.5047078","subitem_relation_type_select":"DOI"}}]},"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":"Masuyama, Y."}],"nameIdentifiers":[{"nameIdentifier":"499672","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mizuno, K."}],"nameIdentifiers":[{"nameIdentifier":"499673","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ozawa, H."}],"nameIdentifiers":[{"nameIdentifier":"499674","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ishiwata, H."}],"nameIdentifiers":[{"nameIdentifier":"499675","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hatano, Y."}],"nameIdentifiers":[{"nameIdentifier":"499676","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohshima, Takeshi"}],"nameIdentifiers":[{"nameIdentifier":"499677","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iwasaki, T."}],"nameIdentifiers":[{"nameIdentifier":"499678","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hatano, M."}],"nameIdentifiers":[{"nameIdentifier":"499679","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大島 武","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"499680","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":"Extending coherence time of macro-scale diamond magnetometer by dynamical decoupling with coplanar waveguide resonator","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Extending coherence time of macro-scale diamond magnetometer by dynamical decoupling with coplanar waveguide resonator"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-01-18"},"publish_date":"2019-01-18","publish_status":"0","recid":"49473","relation_version_is_last":true,"title":["Extending coherence time of macro-scale diamond magnetometer by dynamical decoupling with coplanar waveguide resonator"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:19:33.124486+00:00"}
