The comparison of the ionic conductivity estimated numerically from the parameters obtained experimentally for the Li-diffusion in ＄LiMn_{2}O_{4}＄ with the bulk conductivity indicates that the Li-diffusion seems difficult to play the primary role in the electrical conduction. Instead, a hopping-process of nonadiabatic small polarons of ＄e_{g}＄ electrons is likely to dominate predominantly the electrical transport properties. The dielectric relaxation process, and the activation energies and the pre-exponential factors of the bulk conductivities in ＄Li_{0.95}Mn_{2}O_{4}＄ and ＄LiMn_{1.95}B_{0.05}O_{4}＄ are explained self-consistently in terms of the polaronic conduction.","subitem_description_type":"Abstract"}]},"item_2_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"ナカツガワ, ヒロシ"}]}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{}]}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Institute of Physics"}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1063/1.1432123","subitem_relation_type_select":"DOI"}}]},"item_2_relation_44":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://link.aip.org/link/?JAPIAU/91/2149/1"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://link.aip.org/link/?JAPIAU/91/2149/1","subitem_relation_type_select":"URI"}}]},"item_2_rights_14":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright 2002 by the American Institute of Physics."}]},"item_2_rights_15":{"attribute_name":"権利URI","attribute_value_mlt":[{"subitem_rights":"http://www.aip.org/ | http://www.aip.org/"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00693547","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00218979","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Iguchi, E."}],"nameIdentifiers":[{"nameIdentifier":"17416","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tokuda, Y."}],"nameIdentifiers":[{"nameIdentifier":"17417","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakatsugawa, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"17418","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Munakata, F."}],"nameIdentifiers":[{"nameIdentifier":"17419","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":"2016-09-16"}],"displaytype":"detail","filename":"JAP91-2002.pdf","filesize":[{"value":"104.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JAP91-2002.pdf","url":"https://ynu.repo.nii.ac.jp/record/3926/files/JAP91-2002.pdf"},"version_id":"2627877f-8a37-40f5-920f-410c58dae9b1"}]},"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":"Electrical transport properties in ＄LiMn_{2}O_{4}＄, ＄Li_{0..95}Mn_{2}O_{4}＄, and ＄LiMn_{1.95}B_{0.05}O_{4}＄ (B=Al or Ga) around room temperature","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Electrical transport properties in ＄LiMn_{2}O_{4}＄, ＄Li_{0..95}Mn_{2}O_{4}＄, and ＄LiMn_{1.95}B_{0.05}O_{4}＄ (B=Al or Ga) around room temperature"}]},"item_type_id":"2","owner":"3","path":["496"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-12-14"},"publish_date":"2009-12-14","publish_status":"0","recid":"3926","relation_version_is_last":true,"title":["Electrical transport properties in ＄LiMn_{2}O_{4}＄, ＄Li_{0..95}Mn_{2}O_{4}＄, and ＄LiMn_{1.95}B_{0.05}O_{4}＄ (B=Al or Ga) around room temperature"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T21:36:40.372551+00:00"}
