It is assumed that the oddth bond is antiferromagnetic with strength J and even-th bond can take the values JA and JF (JA > J > 0 > JF) randomly. The ground state of this model interpolates between the Haldane and dimer phases via a randomness dominated intermediate phase. Based on the scaling of the low energy spectrum and mean field treatment of the interchain coupling, it is found that the magnetic long range order is induced by randomness in the intermediate regime. In the magnetization curves, there appears a plateau at the fractional value of thesaturated magnetization. The fine structures of the magnetization curves and low energy spectrum are understood based on the cluster picture. The relation with the recent experiment for (CH3)2CHNH3Cu(ClxBr1−x)3 is discussed.","subitem_description_type":"Abstract"}]},"item_119_description_21":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"Copyright(c)2003 The Physical Society of Japan","subitem_description_type":"Other"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"Physical Society of Japan"}]},"item_119_relation_16":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1143/JPSJ.72.688","subitem_relation_type_select":"DOI"}}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00319015","subitem_source_identifier_type":"ISSN"}]},"item_119_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[著者版]"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"Hida, Kazuo"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1001097"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学大学院理工学研究科"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Science and Engineering, Saitama University"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2003"}]},"item_119_version_type_28":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"飛田, 和男"},{"creatorName":"ヒダ, カズオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"A1001097.pdf","filesize":[{"value":"247.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1001097.pdf","url":"https://sucra.repo.nii.ac.jp/record/12521/files/A1001097.pdf"},"version_id":"e8947e15-f37d-4f8a-9e07-65bc021f85e2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"random quantum spin chain","subitem_subject_scheme":"Other"},{"subitem_subject":"bond alternation","subitem_subject_scheme":"Other"},{"subitem_subject":"DMRG","subitem_subject_scheme":"Other"},{"subitem_subject":"disorder induced order","subitem_subject_scheme":"Other"},{"subitem_subject":"magnetization plateau","subitem_subject_scheme":"Other"}]},"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":"Random magnetism in S=1/2 Heisenberg chains with bond alternation and randomness on the strong bonds","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Random magnetism in S=1/2 Heisenberg chains with bond alternation and randomness on the strong bonds"}]},"item_type_id":"119","owner":"3","path":["426"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-03-08"},"publish_date":"2007-03-08","publish_status":"0","recid":"12521","relation_version_is_last":true,"title":["Random magnetism in S=1/2 Heisenberg chains with bond alternation and randomness on the strong bonds"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T13:02:01.497698+00:00"}
