The non-ergodic and highly degenerate landscape of the spin glass phase at low temperature explains the origin of complex magnetic texture in the FeCo/FePt system. Upon cooling the bilayered system, the magnetic texture undergoes spin freezing below 120 K as evident from the bifurcations in zero field cooling and field cooling magnetizations at low magnetic field as a manifestation of broken ergodicity. The uncompensated magnetic moments originating in the spin glass state result in slow time dynamics of thermoremanent magnetization. Consequently, the bilayers demonstrate an intriguing magnetic memory effect in which the magnetic state of the system could be retrieved upon isothermal ageing below 120 K after reversing the temperature cycle. Thermal treatment deteriorates the spin glass behaviour and shows a transition to strong ferromagnetic character in FeCo/FePt bilayers.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_30002_file35":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"10449329.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://kyutech.repo.nii.ac.jp/record/2001405/files/10449329.pdf"},"version_id":"159c8820-4051-45f7-a600-2b97e4639987"}]},"item_30002_language12":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_30002_publisher10":{"attribute_name":"出版社","attribute_value_mlt":[{"subitem_publisher":"IOP Publishing","subitem_publisher_language":"en"}]},"item_30002_resource_type13":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_30002_source_identifier22":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA00704905","subitem_source_identifier_type":"NCID"}]},"item_30002_title0":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Peculiar spin glass phase emerging in FeCo/FePt driven via nanoconfined crystallographic distortions","subitem_title_language":"en"}]},"item_30002_version_type15":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_title":"Peculiar spin glass phase emerging in FeCo/FePt driven via nanoconfined crystallographic distortions","item_type_id":"40001","owner":"12","path":["9"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2025-03-03"},"publish_date":"2025-03-03","publish_status":"0","recid":"2001405","relation_version_is_last":true,"title":["Peculiar spin glass phase emerging in FeCo/FePt driven via nanoconfined crystallographic distortions"],"weko_creator_id":"12","weko_shared_id":-1},"updated":"2025-07-07T07:53:21.578429+00:00"}
