A novel magnetic transition was found atB > 100 T and T >T * = 32 ± 5 K, which is characterized by its transition field increasing with increasing temperature. At T <T*, the previously reported transition at B ∼ 65 T was observed. Based on the obtained B-T phase diagram and the Clausius-Clapeyron relation, the entropy of the high-field phase at 80 K is found to be smaller for about 1.5 J K-1 mol-1 than that of the low-field phase.We suggest that the observed two high-field phasesmay originate in different spatial orders of the spin states and possibly other degrees of freedom such as orbitals. An inherent strong correlation of spin states among cobalt sites should have triggered the emergence of the ordered phases in LaCoO3 at high magnetic fields.","subitem_description_type":"Abstract"}]},"item_2_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"UTokyo Research掲載「半世紀に渡るコバルト酸化物の謎を解き明かす」 URI: http://www.u-tokyo.ac.jp/ja/utokyo-research/research-news/solving-the-problem-of-half-a-century-over-cobalt-oxides.html","subitem_description_type":"Other"},{"subitem_description":"UTokyo Research \"Solving the problem of half a century over cobalt oxides\" URI: http://www.u-tokyo.ac.jp/en/utokyo-research/research-news/solving-the-problem-of-half-a-century-over-cobalt-oxides.html","subitem_description_type":"Other"}]},"item_2_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Physical Society"}]},"item_2_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1103/PhysRevB.93.220401","subitem_relation_type_select":"DOI"}}]},"item_2_relation_25":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_type":"isReferencedBy","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.u-tokyo.ac.jp/focus/ja/articles/a_00494.html","subitem_relation_type_select":"URI"}},{"subitem_relation_type":"isReferencedBy","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.u-tokyo.ac.jp/focus/en/articles/a_00485.html","subitem_relation_type_select":"URI"}},{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1103/PhysRevB.93.220401","subitem_relation_type_select":"DOI"}}]},"item_2_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2016 American Physical Society"}]},"item_2_select_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_2_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1550235X","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Institute for Solid State Physics, University of Tokyo"},{"subitem_text_value":"Ibaraki National College of Technology, Department of Natural Science"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ikeda, Akihiko"}],"nameIdentifiers":[{"nameIdentifier":"3826","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nomura, Toshihiro"}],"nameIdentifiers":[{"nameIdentifier":"3827","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsuda, Yasuhiro H."}],"nameIdentifiers":[{"nameIdentifier":"3828","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsuo, Akira"}],"nameIdentifiers":[{"nameIdentifier":"3829","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kindo, Koichi"}],"nameIdentifiers":[{"nameIdentifier":"3830","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sato, Keisuke"}],"nameIdentifiers":[{"nameIdentifier":"3831","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":"2017-05-30"}],"displaytype":"detail","filename":"PhysRevB.93.220401.pdf","filesize":[{"value":"539.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"PhysRevB.93.220401.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/945/files/PhysRevB.93.220401.pdf"},"version_id":"e428c540-30e9-46ee-be34-2c7e1e4c7701"}]},"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":"Spin state ordering of strongly correlating LaCoO3 induced at ultrahigh magnetic fields","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Spin state ordering of strongly correlating LaCoO3 induced at ultrahigh magnetic fields","subitem_title_language":"en"}]},"item_type_id":"2","owner":"1","path":["11","178"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-01-16"},"publish_date":"2017-01-16","publish_status":"0","recid":"945","relation_version_is_last":true,"title":["Spin state ordering of strongly correlating LaCoO3 induced at ultrahigh magnetic fields"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-10T05:41:05.575184+00:00"}
