Here we report that alignment occur for ordinary solid that do not contain spontaneous moment; alignment occurred by anisotropy of magnetic susceptibility Delta(sub chi). Rotational oscillation of a magnetically stable axis with respect to static field was observed for biotite, calcite, forsterite, graphite, muscovite, talc and urea at a low field of 0.11 T produced by a horseshoe magnet. Delta(sub chi) above 4 x 10(exp -8) emu/g are obtained from the period of oscillation tau = 2 pi x (I/(M x Delta(sub chi)))(exp -1/2) x B(exp -1); this was realized because restoration torque of the fiber that suspended the crystal was negligible. Sensitivity for measuring Delta(sub chi) can be improved drastically by realizing the oscillation in microgravity, where the fiber itself is deleted; oscillations were achieved for KDP (Potassium Dihydrogen Phosphate), gypsum, Rochelle salt and urea at B = 1.3 T. Higher sensitivity is necessary to obtain small Delta(sub chi) values; this can be done by increasing tau according to the above equation, and is realized by a parabolic flight or in an orbital laboratory. Characteristics of spontaneous moment have long been conceived to the public by rotational oscillation of a compass caused by terrestrial field, which led to invention of the above mentioned devices. In a same sense, rotational motions of ordinary crystals reported here may induce new types of applications in various fields that are not related to magnetism at present. Magnetically active property may be recognized for almost all the solid materials when sensitivity of Delta(sub chi) reach the level of 10(exp -11) emu/g in an parabolic flight.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063349008","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/ISAS)"}]},"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"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Osaka University Graduate School of Science"}]},"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":"63349008.pdf","filesize":[{"value":"468.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"63349008.pdf","url":"https://jaxa.repo.nii.ac.jp/record/13506/files/63349008.pdf"},"version_id":"967313ce-afb0-43ba-a191-23b6abe17b2e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"反磁性","subitem_subject_scheme":"Other"},{"subitem_subject":"異方性","subitem_subject_scheme":"Other"},{"subitem_subject":"磁気特性","subitem_subject_scheme":"Other"},{"subitem_subject":"磁化率","subitem_subject_scheme":"Other"},{"subitem_subject":"反磁性異方性","subitem_subject_scheme":"Other"},{"subitem_subject":"磁場配向","subitem_subject_scheme":"Other"},{"subitem_subject":"磁気振動","subitem_subject_scheme":"Other"},{"subitem_subject":"回転振動","subitem_subject_scheme":"Other"},{"subitem_subject":"微小重力","subitem_subject_scheme":"Other"},{"subitem_subject":"感度","subitem_subject_scheme":"Other"},{"subitem_subject":"測定装置","subitem_subject_scheme":"Other"},{"subitem_subject":"磁場","subitem_subject_scheme":"Other"},{"subitem_subject":"放物線飛行","subitem_subject_scheme":"Other"},{"subitem_subject":"diamagnetism","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"anisotropy","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"magnetic property","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"magnetic susceptibility","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"diamagnetic anisotropy","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"magnetic alignment","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"magnetic oscillation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"rotational oscillation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"microgravity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sensitivity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"measuring instrument","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"magnetic field","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"parabolic flight","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":"浮遊試料の磁気回転振動を用いた高感度での磁場配向特性の検出","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"浮遊試料の磁気回転振動を用いた高感度での磁場配向特性の検出"}]},"item_type_id":"5","owner":"1","path":["1644","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"13506","relation_version_is_last":true,"title":["浮遊試料の磁気回転振動を用いた高感度での磁場配向特性の検出"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T05:53:12.208202+00:00"}
