An electrochemically etched a single-crystalline W<001> tip was cleaned in ultrahigh vacuum by field evaporation process. Cr was in-situ deposited with electron bombardment evaporation at room temperature. Subsequently, in order to improve the crystallinity of the Cr thin film, the tip was annealed 750K. The surface structure of the Cr/W(001) tip was observed by using field ion microscope with hydrogen as imaging gas. FIM image shows that Cr layers was grown pseudomorphically on W(001). Then we measure spin polarization from Cr/W(001) plane. The maximum of spin polarization of electrons field-emitted from the emitter was 20% at 150 K. Investigation that effects of the surface structure of the Cr thin film and adsorption of gas atoms on the spin polarization has been progressed.","subitem_description_type":"Abstract"}]},"item_8_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"2013年度～2014年度科学研究費補助金(若手研究（B）)研究成果報告書","subitem_description_type":"Other"}]},"item_8_description_64":{"attribute_name":"科研費番号","attribute_value_mlt":[{"subitem_description":"25870326","subitem_description_type":"Other"}]},"item_8_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_8_text_18":{"attribute_name":"その他のタイトル","attribute_value_mlt":[{"subitem_text_value":"Development of a spin-rotatable spin-polarized field emitter"}]},"item_8_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Kaken / 科研費報告書"}]},"item_8_version_type_15":{"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":"永井, 滋一","creatorNameLang":"ja"},{"creatorName":"NAGAI, Shigekazu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"25183","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":"2017-02-20"}],"displaytype":"detail","filename":"40K17931.pdf","filesize":[{"value":"930.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"40K17931.pdf","url":"https://mie-u.repo.nii.ac.jp/record/10127/files/40K17931.pdf"},"version_id":"b813c4e5-6954-422a-953a-586804f98280"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"電界放出型電子源","subitem_subject_scheme":"Other"},{"subitem_subject":"スピン偏極電子源","subitem_subject_scheme":"Other"},{"subitem_subject":"反強磁性体","subitem_subject_scheme":"Other"},{"subitem_subject":"層間反強磁性体","subitem_subject_scheme":"Other"}]},"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":"自己スピン回転機能を有する電界放出型スピン偏極電子源の開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"自己スピン回転機能を有する電界放出型スピン偏極電子源の開発","subitem_title_language":"ja"}]},"item_type_id":"8","owner":"15","path":["1692685139729"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-01-13"},"publish_date":"2017-01-13","publish_status":"0","recid":"10127","relation_version_is_last":true,"title":["自己スピン回転機能を有する電界放出型スピン偏極電子源の開発"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-11-17T02:34:19.295141+00:00"}
