Based on this theoretical expectation we manufctured a biaxial 6-81 Mo permalloy core with a dimension ratio of as high as l/d = 2.0 × 10^3, where length l = 500 mm, thickness h = 10 μm, width w = 5 mm, and d = 2 &radic; h・w/π. A drive current applied on the core with a 1-kHz frequency makes a 2-kHz pick-up current which is amplified and phase-detected. The output voltage from the phase detector stands for the magnetic field strength along the core axis. Geomagnetic field variations are recorded by this 50-cm biaxial magnetometer at the Onagawa Magnetic Observatory of Tohoku University and compared with those recorded simultaneously by another commercial biaxial magnetometer. It is concluded that this 50-cm biaxial one is very excellent magnetometer with resolution of 10^<-2> nT (100 times better than the commercial type) and with sensitivity of 10 mV/nT (～100 times better).","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0125706000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学宇宙航空研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0563-8100","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00161914","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東北工業大学"},{"subitem_text_value":"東北工業大学"},{"subitem_text_value":"東北大学理学部"},{"subitem_text_value":"東北大学理学部"},{"subitem_text_value":"東北大学理学部"},{"subitem_text_value":"東北大学理学部"},{"subitem_text_value":"東北大学理学部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"瀬戸, 正弘"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"早坂, 孝"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"斎藤, 尚生"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"桜井, 享"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田村, 忠義"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"湯元, 清文"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐々木, 徹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SETO, Masahiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HAYASAKA, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SAITO, Takao","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SAKURAI, Tohru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAMURA, Tadayoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YUMOTO, Kiyohumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SASAKI, Tohru","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-24"}],"displaytype":"detail","filename":"SA0125706.pdf","filesize":[{"value":"941.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0125706.pdf","url":"https://jaxa.repo.nii.ac.jp/record/32453/files/SA0125706.pdf"},"version_id":"33c65df9-cb6e-421b-a03e-ee28c0e6d7fd"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"<論文>50cm長BIAXIAL型-CORE型FLUXGATE磁力計の製作","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"<論文>50cm長BIAXIAL型-CORE型FLUXGATE磁力計の製作"}]},"item_type_id":"9","owner":"1","path":["1890","1910"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"32453","relation_version_is_last":true,"title":["<論文>50cm長BIAXIAL型-CORE型FLUXGATE磁力計の製作"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:31:58.237943+00:00"}
