Due to the effect of the in-plane ferromagnetic fluctuations enhanced for 0:6 \u003c x \u003c 0.75, the quasiparticle dispersion near the \u0393-point is strongly reduced to yield an almost flat dispersion just above the fermi level. With increasing x, the electronic specifc heat coefficient \u03b3increases towards the critical doping xc \uff5e 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": "\u51fa\u7248\u8005", "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": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "author"}]}, "item_5_source_id_11": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "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": "\u8457\u8005", "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": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "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": "\u30ad\u30fc\u30ef\u30fc\u30c9", "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": "\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": "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": "\u30bf\u30a4\u30c8\u30eb", "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": ["453/454", "176/488/489"], "permalink_uri": "http://hdl.handle.net/10191/26879", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "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}
