We investigated the crystallographic structure of an isotropic Nd2Fe14B magnet comprising nanocrystals of a size of ~30 nm at pressures up to 2 GPa. The results of X-ray diffraction measurements using Rietveld refinement revealed the displacements of each Fe atomic site in the Fe cluster, Nd, and B atomic sites. The lattice constants, a and c, of tetragonal symmetry decreased proportionally with external pressure, whereas the shrinkage ratio for both a and c changed at approximately 0.5 GPa. However, each atomic position exhibited non-monotonic pressure dependence. The trend of displacement of atomic positions changed at a characteristic pressure of 0.4 ± 0.1 GPa. When exceeded, most atoms shifted to the direction opposite their displacement at lower pressures. Thus, they exhibited restoration tendencies toward the positions at ambient pressure. The bond angles and bond lengths among Nd, Fe, and B atoms also exhibited characteristic pressure dependences. As pressure increased, the basal triangle of the trigonal prism in the Fe cluster layers distorted up to ~0.5 GPa, whereas the strain of the trigonal prism gradually reduced just above 0.5 GPa. The atomic position of the heaviest Nd atoms was a key structural parameter to characterize the change.","subitem_description_type":"Abstract"}]},"item_21_description_60":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Journal Article","subitem_description_type":"Other"}]},"item_21_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"31820","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Tajiri,  T."}]},{"affiliations":[{"affiliationNames":[{"affiliationName":"","lang":"ja"}],"nameIdentifiers":[]}],"familyNames":[{"familyName":"Mito","familyNameLang":"en"},{"familyName":"美藤","familyNameLang":"ja"},{"familyName":"ミトウ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Masaki","givenNameLang":"en"},{"givenName":"正樹","givenNameLang":"ja"},{"givenName":"マサキ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"1968","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"60315108","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000060315108"},{"nameIdentifier":"7005569176","nameIdentifierScheme":"Scopus著者ID","nameIdentifierURI":"https://www.scopus.com/authid/detail.uri?authorId=7005569176"},{"nameIdentifier":"139","nameIdentifierScheme":"九工大研究者情報","nameIdentifierURI":"https://hyokadb02.jimu.kyutech.ac.jp/html/139_ja.html"}],"names":[{"name":"Mito, Masaki","nameLang":"en"},{"name":"美藤, 正樹","nameLang":"ja"},{"name":"ミトウ, マサキ","nameLang":"ja-Kana"}]}]},"item_21_link_62":{"attribute_name":"研究者情報","attribute_value_mlt":[{"subitem_link_url":"https://hyokadb02.jimu.kyutech.ac.jp/html/139_ja.html"}]},"item_21_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_21_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.jmmm.2019.166163","subitem_relation_type_select":"DOI"}}]},"item_21_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (c) 2019 Elsevier B.V.
