Due to the effect of the in-plane ferromagnetic fluctuations enhanced for 0:6 \u003c x \u003c 0.75, the quasiparticle dispersion near the Γ-point is strongly reduced to yield an almost flat dispersion just above the fermi level. With increasing x, the electronic specifc heat coefficient γincreases towards the critical doping xc ～ 0.75 above which the in-plane ferromagnetism takes place. We also find that the six small hole pockets near the K-point are stabilized due to the electron correlation effect within both the SOP and the RPA.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Elsevier"}]}, "item_5_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.1016/j.jpcs.2008.06.078", "subitem_relation_type_select": "DOI"}}]}, "item_5_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "author"}]}, "item_5_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA00704949", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "00223697", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Yanagi, Yuki"}], "nameIdentifiers": [{"nameIdentifier": "6807", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ono, Yoshiaki"}], "nameIdentifiers": [{"nameIdentifier": "62", "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": "2019-07-29"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "995.pdf", "filesize": [{"value": "217.1 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 217100.0, "url": {"label": "995.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/2057/files/995.pdf"}, "version_id": "d0141ade-3579-4fc5-be35-6579f68ee363"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "NaxCoO2", "subitem_subject_scheme": "Other"}, {"subitem_subject": "ferromagnetic spin fluctuations", "subitem_subject_scheme": "Other"}, {"subitem_subject": "RPA", "subitem_subject_scheme": "Other"}, {"subitem_subject": "electronic specific heat", "subitem_subject_scheme": "Other"}, {"subitem_subject": "renormalized band", "subitem_subject_scheme": "Other"}, {"subitem_subject": "mass enhancement", "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": "Effect of ferromagnetic spin fluctuations on the electronic states in NaxCoO2 based on two-dimensional triangular lattice 11-band d-p model", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Effect of ferromagnetic spin fluctuations on the electronic states in NaxCoO2 based on two-dimensional triangular lattice 11-band d-p model"}, {"subitem_title": "Effect of ferromagnetic spin fluctuations on the electronic states in NaxCoO2 based on two-dimensional triangular lattice 11-band d-p model", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "489"], "permalink_uri": "http://hdl.handle.net/10191/26879", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-04-16"}, "publish_date": "2014-04-16", "publish_status": "0", "recid": "2057", "relation": {}, "relation_version_is_last": true, "title": ["Effect of ferromagnetic spin fluctuations on the electronic states in NaxCoO2 based on two-dimensional triangular lattice 11-band d-p model"], "weko_shared_id": null}
