Due to the effect of the in-plane ferromagnetic fluctuations enhanced for 0:6 < x < 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","filename":"995.pdf","filesize":[{"value":"217.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","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"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-04-16"},"publish_date":"2014-04-16","publish_status":"0","recid":"2057","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_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:34:51.490953+00:00"}
