Large magnetoresistance ratio of ∼25% and resistance change-area product of ∼7.5 mΩ μm2 were obtained at room temperature by inserting a CFBT (1.2 nm) underlayer. X-ray diffraction (XRD) and transmission electron microscope analyses confirmed that the CMFG FM layer deposited on the CFBT underlayer was amorphous in the as-deposited state and crystallized to a B2-ordered polycrystalline film by annealing at 300 °C. The degree of B2 order (SB2) of the CMFG films was estimated by anomalous XRD using x-ray energies around the Co K-absorption edge. SB2 of the CMFG film deposited on the amorphous CFBT (1.2 nm) underlayer was ∼0.76, much larger than that of the CMFG film deposited on a crystalline CoFe underlayer (SB2 ∼0.47). First-principles calculations indicated that the spin polarization of the sp-conduction electrons in CMFG increases with increasing SB2, which accounts for the enhanced CPP-GMR effect in the pseudo spin-valve by inserting an amorphous CFBT underlayer.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":" Elsevier"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.actamat.2017.09.046","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://www.sciencedirect.com/science/article/pii/S1359645417308121"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.sciencedirect.com/science/article/pii/S1359645417308121","subitem_relation_type_select":"URI"}}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"李, 松田"}],"nameIdentifiers":[{"nameIdentifier":"499094","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakatani, T"}],"nameIdentifiers":[{"nameIdentifier":"499095","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Masuda, K"}],"nameIdentifiers":[{"nameIdentifier":"499096","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakuraba, Y"}],"nameIdentifiers":[{"nameIdentifier":"499097","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Xu, XD"}],"nameIdentifiers":[{"nameIdentifier":"499098","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sasaki, TT"}],"nameIdentifiers":[{"nameIdentifier":"499099","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tajiri, H"}],"nameIdentifiers":[{"nameIdentifier":"499100","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Miura, Y"}],"nameIdentifiers":[{"nameIdentifier":"499101","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Furubayashi, T"}],"nameIdentifiers":[{"nameIdentifier":"499102","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hono, K"}],"nameIdentifiers":[{"nameIdentifier":"499103","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"李 松田","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"499104","nameIdentifierScheme":"WEKO"}]}]},"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":"Enhancement of current-perpendicular-to-plane giant magnetoresistive outputs by improving B2-order in polycrystalline Co2(Mn0.6Fe0.4)Ge Heusler alloy films with the insertion of amorphous CoFeBTa underlayer","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Enhancement of current-perpendicular-to-plane giant magnetoresistive outputs by improving B2-order in polycrystalline Co2(Mn0.6Fe0.4)Ge Heusler alloy films with the insertion of amorphous CoFeBTa underlayer"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-01-09"},"publish_date":"2019-01-09","publish_status":"0","recid":"49414","relation_version_is_last":true,"title":["Enhancement of current-perpendicular-to-plane giant magnetoresistive outputs by improving B2-order in polycrystalline Co2(Mn0.6Fe0.4)Ge Heusler alloy films with the insertion of amorphous CoFeBTa underlayer"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:19:55.034585+00:00"}
