Herein, we study the effect of moderate annealing (450°C) on strongly interacting NiCr nanoparticle assemblies (0 <= atom % Cr ≤ 15) immediately after deposition. Concurrent temperature-dependent electron microscopy and magnetization data demonstrate the interplay of two competing factors, namely, enhanced particle aggregation and element-specific surface segregation, on the magnetic properties, with the former boosting and the latter suppressing them. Strong interparticle interactions can lead to a magnetic response different from that of superparamagnetic particles, namely, from canonical spin-glass (0 atom % Cr) to correlated spin-glass (5-15 atom % Cr) behavior below higher spin-glass transition temperatures T-g (20-350 K). The observation of \"high-field susceptibility\" below cryogenic temperatures (≤20 K) is ascribed to the presence of inhomogeneity/defects caused by Cr segregation. This work emphasizes the necessity of taking into account the delicate balance of such competing factors to understand the magnetic properties of nanoparticulate samples.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"American Chemical Society "}]},"item_10001_relation_13":{"attribute_name":"PubMedNo.","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:pmid/33403249","subitem_relation_type_select":"PMID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1021/acsomega.0c03056","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"Related site","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://pubs.acs.org/doi/10.1021/acsomega.0c03056","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"Rights","attribute_value_mlt":[{"subitem_rights":"© 2020 American Chemical Society."}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2470-1343","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"Author's flag","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-02-19"}],"displaytype":"detail","filename":"Bohra-2020-Aggregation vs Surface Segregation_.pdf","filesize":[{"value":"2.2 MB"}],"format":"application/pdf","license_note":" ACS AuthorChoice (https://pubs.acs.org/page/policy/authorchoice_termsofuse.html)","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Bohra-2020-Aggregation vs Surface Segregation_","url":"https://oist.repo.nii.ac.jp/record/1939/files/Bohra-2020-Aggregation vs Surface Segregation_.pdf"},"version_id":"98f7a74b-b149-44d1-ab52-c4fc0fdc2d30"}]},"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":"Aggregation vs Surface Segregation: Antagonism over the Magnetic Behavior of NiCr Nanoparticles","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Aggregation vs Surface Segregation: Antagonism over the Magnetic Behavior of NiCr Nanoparticles","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"30","path":["58"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-02-19"},"publish_date":"2021-02-19","publish_status":"0","recid":"1939","relation_version_is_last":true,"title":["Aggregation vs Surface Segregation: Antagonism over the Magnetic Behavior of NiCr Nanoparticles"],"weko_creator_id":"30","weko_shared_id":30},"updated":"2023-06-26T11:40:00.852549+00:00"}
