We first present the coherent potential formula using t matrix elements of the s-f exchange interaction. Applying the mean field theory to fluctuating f spins, the variation of the electric state density with temperature is investigated for various strengths of s-f exchange interaction. The anomalous redshift of the optical absorption edge, and the dependence of the electron-spin polarization and electrical resistivity on the temperature and magnetic fields, experimentally observed in EuO and EuS, can be explained consistently within this approximation. The effect of f spin correlation on the s electron states is also discussed.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34411/00000850","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"神奈川工科大学"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10074179","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09161902","subitem_source_identifier_type":"PISSN"}]},"item_10002_version_type_20":{"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":"高橋, 正雄","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"Takahashi, Masao","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2010-02-03"}],"displaytype":"detail","filename":"kkb-023-021.pdf","filesize":[{"value":"3.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kkb-023-021.pdf","objectType":"fulltext","url":"https://kait.repo.nii.ac.jp/record/857/files/kkb-023-021.pdf"},"version_id":"51b107fc-e0e6-46a3-b141-4a25652b77fd"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"diluted magnetic semiconductor (DMS)","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"exchange interaction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"coherent potential approximation (CPA)","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Coherent Potential Approach to the s-f Model in Magnetic Semiconductors","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Coherent Potential Approach to the s-f Model in Magnetic Semiconductors","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"4","path":["113"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-11-24"},"publish_date":"2020-11-24","publish_status":"0","recid":"857","relation_version_is_last":true,"title":["Coherent Potential Approach to the s-f Model in Magnetic Semiconductors"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2023-08-04T09:00:51.297254+00:00"}
