By using ab initio calculations along with Monte Carlo simulations and nonequilibrium Green’s function method, we demonstrate that the transition metal oxide monolayer (ML) of Cr2O3 is an ideal candidate for next-generation spintronics applications. 2D Cr2O3 has honeycomb-kagome lattice, where the Dirac and strongly correlated fermions coexist around the Fermi level. Furthermore, the spin exchange coupling constant shows strong ferromagnetic (FM) interaction between Cr atoms. Cr2O3 ML has a robust half-metallic behavior with a large spin gap of ~3.9 eV and adequate Curie temperature. Interestingly, an intrinsic Ising FM characteristic is observed with a giant perpendicular magnetocrystalline anisotropy energy of ~0.9 meV. Most remarkably, nonequilibrium Green’s function calculations reveal that the Cr2O3 ML exhibits an excellent spin filtering effect.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Nature"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1038/s41699-020-00174-0","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://www.nature.com/articles/s41699-020-00174-0","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2397-7132","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":"Hashmi"}],"nameIdentifiers":[{"nameIdentifier":"1003025","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakanishi, Kenta"}],"nameIdentifiers":[{"nameIdentifier":"1003026","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Umar Farooq, Muhammad"}],"nameIdentifiers":[{"nameIdentifier":"1003027","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ono, Tomoya"}],"nameIdentifiers":[{"nameIdentifier":"1003028","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hashmi, Arqum","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1003029","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":"Ising ferromagnetism and robust half-metallicity in two-dimensional honeycomb-kagome Cr2O3 layer","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Ising ferromagnetism and robust half-metallicity in two-dimensional honeycomb-kagome Cr2O3 layer"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-07-15"},"publish_date":"2020-07-15","publish_status":"0","recid":"80954","relation_version_is_last":true,"title":["Ising ferromagnetism and robust half-metallicity in two-dimensional honeycomb-kagome Cr2O3 layer"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:31:45.087501+00:00"}
