We find that a field-suppression effect on the longitudinal thermal conductivity K-xx, sets in below approximately 25 K. This field-suppression effect at 15 T becomes as large as 80% at low temperatures, suggesting a large spin contribution  [Formula: see text] in K-xx. We also find clear thermal Hall signals in the spin liquid phase in all Cd-K samples. The magnitude of the thermal Hall conductivity K-xy shows a significant dependence on the sample's scattering time, as seen in the rise of the peak K-xy value in almost linear fashion with the magnitude of K-xx. On the other hand, the temperature dependence of K-xy is similar in all Cd-K samples; K-xy shows a peak at almost the same temperature of the peak of the phonon thermal conductivity [Formula: see text] which is estimated by K-xx, at 15 T. These results indicate the presence of a dominant phonon thermal Hall [Formula: see text] at 15 T. In addition to [Formula: see text], we find that the field dependence of K-xy at low fields turns out to be nonlinear at low temperatures, concomitantly with the appearance of the field suppression of K-xx, indicating the presence of a spin thermal Hall  [Formula: see text] at low fields. Remarkably, by assembling the K-xx dependence of  [Formula: see text] data of other kagome antiferromagnets, we find that, whereas  [Formula: see text] stays a constant in the low-K-xx region, [Formula: see text] starts to increase as K-xx does in the high-K-xx region. This K-xx dependence of  [Formula: see text] indicates the presence of both intrinsic and extrinsic mechanisms in the spin thermal Hall effect in kagome antiferromagnets. Furthermore, both  [Formula: see text] and  [Formula: see text], disappear in the antiferromagnetic ordered phase at low fields, showing that phonons alone do not exhibit the thermal Hall effect. A high field above approximately 7 T induces  [Formula: see text], concomitantly with a field-induced increase of K-xx and the specific heat, suggesting a coupling of the phonons to the field-induced spin excitations as the origin of [Formula: see text].","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"American Physical Society."}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1103/PhysRevX.10.041059","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"Related site","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://journals.aps.org/prx/abstract/10.1103/PhysRevX.10.041059","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"Rights","attribute_value_mlt":[{"subitem_rights":"© 2020 American Physical Society."}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2160-3308","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"Author's flag","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-01-18"}],"displaytype":"detail","filename":"Akazawa-2020-Thermal Hall Effects of Spins and.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","license_note":"Creative Commons Attribution 4.0 International(https://creativecommons.org/licenses/by/4.0/)","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Akazawa-2020-Thermal Hall Effects of Spins and","url":"https://oist.repo.nii.ac.jp/record/1885/files/Akazawa-2020-Thermal Hall Effects of Spins and.pdf"},"version_id":"55451648-af10-4a4b-a134-bd7344155676"}]},"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":"Thermal Hall Effects of Spins and Phonons in Kagome Antiferromagnet Cd-Kapellasite","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Thermal Hall Effects of Spins and Phonons in Kagome Antiferromagnet Cd-Kapellasite","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"30","path":["75"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-01-18"},"publish_date":"2021-01-18","publish_status":"0","recid":"1885","relation_version_is_last":true,"title":["Thermal Hall Effects of Spins and Phonons in Kagome Antiferromagnet Cd-Kapellasite"],"weko_creator_id":"30","weko_shared_id":30},"updated":"2023-06-26T11:40:05.281712+00:00"}
