Charge excitations of the hole-doped nickelates are found to be almost independent of momentum transfer, indicating that the doped holes are strongly localized in character. Additionally, conspicuous changes in energy position are in temperature dependence. These characters are observed in stark contrast to those of the high-Tc cuprate La2−xSrxCuO4 (LSCO), where delocalized doped holes form charge excitations with sizable momentum dependence in the CuO2 plane. This distinct nature of charge excitations of doped holes is consistent with the metallicity of the materials and could be caused by strong electron-phonon coupling and weak quantum spin fluctuation in the nickelates.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"アメリカ物理学会"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1103/PhysRevB.102.165145","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://journals.aps.org/prb/abstract/10.1103/PhysRevB.102.165145","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2469-9950","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Yamagami, Kohei"}],"nameIdentifiers":[{"nameIdentifier":"1011988","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ishii, Kenji"}],"nameIdentifiers":[{"nameIdentifier":"1011989","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hirata, Yasuyuki"}],"nameIdentifiers":[{"nameIdentifier":"1011990","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ikeda, Keisuke"}],"nameIdentifiers":[{"nameIdentifier":"1011991","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Miyawaki, Jun"}],"nameIdentifiers":[{"nameIdentifier":"1011992","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Harada, Yoshihisa"}],"nameIdentifiers":[{"nameIdentifier":"1011993","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Miyazaki, Masanori"}],"nameIdentifiers":[{"nameIdentifier":"1011994","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Asano, Shun"}],"nameIdentifiers":[{"nameIdentifier":"1011995","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fujita, Masaki"}],"nameIdentifiers":[{"nameIdentifier":"1011996","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wadati, Hiroki"}],"nameIdentifiers":[{"nameIdentifier":"1011997","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kenji, Ishii","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1011998","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Jun, Miyawaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1011999","nameIdentifierScheme":"WEKO"}]}]},"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":"Localized character of charge excitations for La2−xSrxNiO4+delta revealed by oxygen K-edge resonant inelastic X-ray scattering","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Localized character of charge excitations for La2−xSrxNiO4+delta revealed by oxygen K-edge resonant inelastic X-ray scattering"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-04-03"},"publish_date":"2020-04-03","publish_status":"0","recid":"80800","relation_version_is_last":true,"title":["Localized character of charge excitations for La2−xSrxNiO4+delta revealed by oxygen K-edge resonant inelastic X-ray scattering"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:57:31.587078+00:00"}
