DELTA(X) is expected to range between 10 (exp -7) and 10(exp -11) emu/g according to a recent study based on a model assuming that the individual bonding orbital in the crystal posses constant amount of DELTA(X).  Oscillation of a magnetically stable axis of a crystal with respect to a horizontal field is observed for the purpose of detecting small DELTA(X). Effect of a fiber suspending the crystal is omitted in the measurement; restoration torque of the fiber was a standard in measuring DELTA(X) in conventional methods. DELTA(X) above 4 x 10(exp -8) emu/g are obtained from period of oscillation tau' = 2 pi (I /M DELTA(X))(-1/2)B(exp -1), which was induced at a low field of 0.11 T produced by a horseshoe magnet; here popular materials such as biotite, forsterite, graphite, muscovite, talc and urea were observed. Significant oscillation of bulk nonmagnetic crystals has not been observed at such low field intensity as yet. The system is effective to accumulate DELTA(X) values over a immense number of unmeasured materials in various facilities other than magnetic science that do not posses a strong magnetic-field generator. Sensitivity of DELTA(X) is improved considerably by realizing the above oscillation in microgravity where the fiber itself is deleted; oscillations are achieved for calcite, KDP, gypsum, graphite, Rochelle salt and urea at B=1.3T; sensitivity is expected to be improved to 1 x 10(exp -10) emu/g in ground based facilities. High sensitivity is required to detect smaller DELTA(X) values to the level of 10(exp -11) emu/g; this can be done by increasing tau' according to the above equation in an orbital laboratory. The nature of spontaneous moment was recognized long ago by a rotational oscillation of a compass due to terrestrial field, which led to the invention of important magnetic devices. Significant rotational motions of ordinary nonmagnetic crystals reported in the two experiments mentioned above may induce new devices in various research fields which are not related to magnetism at present.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"},{"subitem_description":"共催: 日本学術会議","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"},{"subitem_description":"Meeting sponsors: The Science Council of Japan, The Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (ISAS)(JAXA)","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064113040","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構宇宙科学研究本部"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10324210","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"大阪大学大学院理学研究科宇宙地球科学専攻"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Earth and Space Science, Graduate school of Science, Osaka University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"植田, 千秋"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ueda, Chiaki","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":"2020-01-20"}],"displaytype":"detail","filename":"64113040.pdf","filesize":[{"value":"368.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64113040.pdf","url":"https://jaxa.repo.nii.ac.jp/record/13657/files/64113040.pdf"},"version_id":"98024ac1-dd76-40be-943b-b4e9b42df3eb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Diamagnetic Anisotropy, Magnetic Oscillation, Microgravity, Magnetic alignment","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"微小重力環境および永久磁石レベルの弱磁場を利用した高感度の反磁性異方性測定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"微小重力環境および永久磁石レベルの弱磁場を利用した高感度の反磁性異方性測定"}]},"item_type_id":"5","owner":"1","path":["1645","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"13657","relation_version_is_last":true,"title":["微小重力環境および永久磁石レベルの弱磁場を利用した高感度の反磁性異方性測定"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T05:48:09.500102+00:00"}
