In contrast to BaFe2As2, where only Fe spins order, EuFe2As2 has an additional magnetic transition below 20 K due to the ordering of the Eu2+ spins (J = 7/2, with L = 0 and S = 7/2) in an A-type antiferromagnetic texture (ferromagnetic layers stacked antiferromagnetically). This may potentially affect the FeAs layer and its local and correlated magnetism. FeKbeta x-ray emission experiments on EuFe2As2 single crystals reveal a local magnetic moment of 1.3 ± 0.15 muB at 15 K that increases slightly to 1.45 +- 0.15 muB at 300 K. Resonant inelastic x-ray scattering experiments performed on the same crystals show dispersive broad (in energy) magnetic excitations along (0,0) -> (1,0) and (0,0) -> (1,1) with a bandwidth on the order of 170-180 meV. These results on local and collective magnetism are in line with other parent compounds of the AFe2As2 series (A = Ba, Ca, and Sr), especially the well-characterized BaFe2As2. Thus, our experiments lead us to the conclusion that the effect of the high magnetic moment of Eu on the magnitude of both the Fe local magnetic moment and spin excitations is small and confined to low-energy excitations.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"the American Physical Society "}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1103/PhysRevB.95.115152","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://link.aps.org/doi/10.1103/PhysRevB.95.115152"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://link.aps.org/doi/10.1103/PhysRevB.95.115152","subitem_relation_type_select":"URI"}}]},"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":"Pelliciari, Jonathan"}],"nameIdentifiers":[{"nameIdentifier":"496507","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ishii, Kenji"}],"nameIdentifiers":[{"nameIdentifier":"496508","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Dantz, Marcus"}],"nameIdentifiers":[{"nameIdentifier":"496509","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Lu, Xingye"}],"nameIdentifiers":[{"nameIdentifier":"496510","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"McNally, Daniel"}],"nameIdentifiers":[{"nameIdentifier":"496511","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"N., Strocov Vladimir"}],"nameIdentifiers":[{"nameIdentifier":"496512","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Xing, Lingyi"}],"nameIdentifiers":[{"nameIdentifier":"496513","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wang, Xiancheng"}],"nameIdentifiers":[{"nameIdentifier":"496514","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Jin, Changqing"}],"nameIdentifiers":[{"nameIdentifier":"496515","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"S., Jeevan Hirale"}],"nameIdentifiers":[{"nameIdentifier":"496516","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Gegenwart, Philipp"}],"nameIdentifiers":[{"nameIdentifier":"496517","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Schmitt, Thorsten"}],"nameIdentifiers":[{"nameIdentifier":"496518","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"石井 賢司","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"496519","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":"Local and collective magnetism of EuFe2As2","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Local and collective magnetism of EuFe2As2"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-10-22"},"publish_date":"2018-10-22","publish_status":"0","recid":"49212","relation_version_is_last":true,"title":["Local and collective magnetism of EuFe2As2"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:20:39.956497+00:00"}
