MCE is induced by the internal magnetic entropy change of magnetic material, thus magnetic refrigeration can operate an ideal cycle like Carnot.\nIn this research, we investigated new magnetic materials that will be useful for hydrogen magnetic refrigeration. It is possible to control temperature and magnetic field dependence of the MCE using magnetic materials with multiple transitions. Magnetic materials of intermetallic compounds such as (ErDy)NiAl, (Er,Dy)Al2, Er(Co,Ni)2, Er(Co,Cu)2 were synthesized. Magnetic and thermal properties of those compounds were measured in order to evaluated MCE. MCE results for oxides, sulfide that have rare-earth elements were also studied as useful materials.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:26420720, 研究期間(年度):2014-04-01 - 2017-03-31","subitem_description_type":"Other"},{"subitem_description":"出典：「多重相転移磁気熱量効果を利用した新規磁性体による高効率水素磁気冷凍の研究」研究成果報告書　課題番号26420720\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-26420720/26420720seika/）を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学理工研究域数物科学系","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00052950","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=10219496"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=10219496","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-26420720/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-26420720/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-26420720/26420720seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-26420720/26420720seika/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-12-20"}],"displaytype":"detail","filename":"SC-PR-MATSUMOTO-K-kaken 2017-6p.pdf","filesize":[{"value":"870.7 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-MATSUMOTO-K-kaken 2017-6p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/46618/files/SC-PR-MATSUMOTO-K-kaken 2017-6p.pdf"},"version_id":"795b07d3-e739-4ae1-97ed-e373c729ae20"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"多重相転移磁気熱量効果を利用した新規磁性体による高効率水素磁気冷凍の研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"多重相転移磁気熱量効果を利用した新規磁性体による高効率水素磁気冷凍の研究"},{"subitem_title":"Hydrogen magnetic refrigeration using new magnetic materials with multiple phase transition","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2817"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-12-20"},"publish_date":"2018-12-20","publish_status":"0","recid":"46618","relation_version_is_last":true,"title":["多重相転移磁気熱量効果を利用した新規磁性体による高効率水素磁気冷凍の研究"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T11:08:25.300182+00:00"}
