The INS spectra are quantitatively explained by spin-1/2 single-tetrahedron model having XXZ anisotropy and Dzyaloshinskii-Moriya interaction. This model has a two-fold degeneracy of the lowest-energy state per tetrahe- dron and well reproduces the magnetization curve at 0.5 K and heat capacity above 1.5 K. At lower temperatures, however, we observe a broad maximum in the heat capacity around 63 mK, demonstrating that a unique quan- tum ground state is selected due to extra perturbations with energy scale smaller than the instrumental resolution of INS.","subitem_description_type":"Abstract"}]},"item_2_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"UTokyo Research掲載「新しいスピン状態を絶対零度付近にて発見」 URI: http://www.u-tokyo.ac.jp/ja/utokyo-research/research-news/new-spin-state-discovered-near-absolute-zero.html","subitem_description_type":"Other"},{"subitem_description":"UTokyo Research \"New spin state discovered near absolute zero\" URI: http://www.u-tokyo.ac.jp/en/utokyo-research/research-news/new-spin-state-discovered-near-absolute-zero.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_25":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.u-tokyo.ac.jp/ja/utokyo-research/research-news/new-spin-state-discovered-near-absolute-zero.html","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.u-tokyo.ac.jp/en/utokyo-research/research-news/new-spin-state-discovered-near-absolute-zero.html","subitem_relation_type_select":"URI"}}]},"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":"2469-9969","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, The University of Tokyo"},{"subitem_text_value":"Division of Materials Physics, Graduate School of Engineering Science, Osaka University"},{"subitem_text_value":"Bragg Institute, Australian Nuclear Science and Technology Organization"},{"subitem_text_value":"Low Temperature Center, Osaka University"},{"subitem_text_value":"Department of Physics, National Cheng Kung University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Haku, T."}],"nameIdentifiers":[{"nameIdentifier":"2761","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kimura, K."}],"nameIdentifiers":[{"nameIdentifier":"2762","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsumoto, Y."}],"nameIdentifiers":[{"nameIdentifier":"2763","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Soda, M."}],"nameIdentifiers":[{"nameIdentifier":"2764","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sera, M."}],"nameIdentifiers":[{"nameIdentifier":"2765","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yu, D."}],"nameIdentifiers":[{"nameIdentifier":"2766","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mole, R.
