Watanabe, H. Yokoyama, Y. Tanaka, and J. Inoue, J. Phys. Soc. Jpn. 75, 074707 (2006)]. We introduce two new trial states: (i) A coexisting state of Ψ^co_Q -antiferromagnetic (AF) and a d-wave singlet gaps, in which we allow for a band renormalization effect, and (ii) a state with an AF order of 120° spin structure. In both states, a first-order metal-to-insulator transition occurs at smaller U/ t than that of the pure d-wave state. In insulating regimes, magnetic orders always exist; an ordinary (π,π)-AF order survives up to t'/t～0.9 (U/ t=12), and a 120°-AF order becomes dominant for t'/ t. The regimes of the robust superconductor and of the nonmagnetic insulator the preceding study proposed give way to these magnetic domains.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/11256"}]},"item_10_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Physical Society","subitem_publisher_language":"en"}]},"item_10_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1103/PhysRevB.77.214505","subitem_relation_type_select":"DOI"}}]},"item_10_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright: American Physical Society, All rights reserved.","subitem_rights_language":"en"}]},"item_10_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_10_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1098-0121","subitem_source_identifier_type":"PISSN"}]},"item_10_text_14":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_text_value":"application/pdf"}]},"item_1615787544753":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Watanabe, T.","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"27000","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yokoyama, H.","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"27001","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tanaka, Y.","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"27002","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Inoue, J.","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"27003","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":"2018-02-20"}],"displaytype":"detail","filename":"PhysRevB_77_214505.pdf","filesize":[{"value":"670.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"PhysRevB_77_214505.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/9475/files/PhysRevB_77_214505.pdf"},"version_id":"a7c970da-e6a6-47c5-b1b6-45ee642e7459"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"antiferromagnetic materials","subitem_subject_scheme":"Other"},{"subitem_subject":"d-wave superconductivity","subitem_subject_scheme":"Other"},{"subitem_subject":"Hubbard model","subitem_subject_scheme":"Other"},{"subitem_subject":"magnetic domains","subitem_subject_scheme":"Other"},{"subitem_subject":"metal-insulator transition","subitem_subject_scheme":"Other"},{"subitem_subject":"Monte Carlo methods","subitem_subject_scheme":"Other"},{"subitem_subject":"organic superconductors","subitem_subject_scheme":"Other"},{"subitem_subject":"renormalisation","subitem_subject_scheme":"Other"},{"subitem_subject":"superconducting energy gap","subitem_subject_scheme":"Other"},{"subitem_subject":"superconducting transitions","subitem_subject_scheme":"Other"},{"subitem_subject":"variational techniques","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":"Predominant magnetic states in the Hubbard model on anisotropic triangular lattices","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Predominant magnetic states in the Hubbard model on anisotropic triangular lattices","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["322"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-03-09"},"publish_date":"2009-03-09","publish_status":"0","recid":"9475","relation_version_is_last":true,"title":["Predominant magnetic states in the Hubbard model on anisotropic triangular lattices"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T03:55:06.098381+00:00"}
