Athough the intensity of saturation magnetization of various rocks is nearly proportional to the amount of Fe_3O_4 contained in them, their coersive force ranges from 60 to 465 Oe. It was further noticed that, as shown in Fig.16, the ratio of intensity of saturated thermo-remanent magnetization in the unit magnetic field to that of saturation magnetization is nearly proportional to the coersive force; in other words, a magnetically hard rock acquires large thermo-remanent magnetization.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"133458","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nagata, Takesi"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000034336","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京帝国大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00029699","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00408972","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"453","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute, Tokyo Imperial University"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"地震研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"永田, 武"}],"nameIdentifiers":[{"nameIdentifier":"133457","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-27"}],"displaytype":"detail","filename":"ji0213004.pdf","filesize":[{"value":"616.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0213004.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/34336/files/ji0213004.pdf"},"version_id":"d5c3ef64-ab69-4bfa-b7c6-83fab2bac740"}]},"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":"15. 火山岩の磁化曲線","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"15. 火山岩の磁化曲線","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["5130","5132"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-06-06"},"publish_date":"2008-06-06","publish_status":"0","recid":"34336","relation_version_is_last":true,"title":["15. 火山岩の磁化曲線"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:09:23.429166+00:00"}
