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 \u03a8^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\u00b0 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 (\u03c0,\u03c0)-AF order survives up to t\u0027/t\uff5e0.9 (U/ t=12), and a 120\u00b0-AF order becomes dominant for t\u0027/ t. The regimes of the robust superconductor and of the nonmagnetic insulator the preceding study proposed give way to these magnetic domains.", "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": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "American Physical Society"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://dx.doi.org/10.1103/PhysRevB.77.214505", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "Copyright: American Physical Society, All rights reserved."}]}, "item_10_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "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": "ISSN"}]}, "item_10_text_14": {"attribute_name": "\u30d5\u30a9\u30fc\u30de\u30c3\u30c8", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Watanabe, T."}], "nameIdentifiers": [{"nameIdentifier": "27000", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yokoyama, H."}], "nameIdentifiers": [{"nameIdentifier": "27001", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tanaka, Y."}], "nameIdentifiers": [{"nameIdentifier": "27002", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Inoue, J."}], "nameIdentifiers": [{"nameIdentifier": "27003", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "PhysRevB_77_214505.pdf", "filesize": [{"value": "670.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 670500.0, "url": {"label": "PhysRevB_77_214505.pdf", "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": "\u30ad\u30fc\u30ef\u30fc\u30c9", "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": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "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": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Predominant magnetic states in the Hubbard model on anisotropic triangular lattices"}]}, "item_type_id": "10", "owner": "1", "path": ["320/321/322"], "permalink_uri": "http://hdl.handle.net/2237/11256", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2009-03-09"}, "publish_date": "2009-03-09", "publish_status": "0", "recid": "9475", "relation": {}, "relation_version_is_last": true, "title": ["Predominant magnetic states in the Hubbard model on anisotropic triangular lattices"], "weko_shared_id": 3}
