The Ne?el temperature of 1.9 K for antiferromagnetic transition at ambient pressure decreases with increasing pressure and vanishes at about 0.33 GPa. The magnetic resistivity, ρm=ρ(Ce7Ni3)-ρ(La 7Ni3), decreases steeply with pressure, and above 0.66 GPa, ρm(T) can be described by the expression ρm(T)=ρm(0)+AT2. The coefficient A decreases and the temperature range in which the T2 dependence is held becomes wider with increasing pressure. The electronic Gru?neisen parameter for the Kondo temperature TK, -∂lnTK/∂lnV, is evaluated to be 132 from the pressure dependence of A. This value is larger than that of typical heavy-fermion compounds. The results are discussed in relation to the competition between the magnetic interaction and the Kondo interaction in Ce7Ni3.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"American Physical Society"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"1098-0121","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AA11187113","subitem_source_identifier_type":"NCID"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"1194"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"1996-07-01","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicPageEnd":"1198","bibliographicPageStart":"1194","bibliographicVolumeNumber":"54","bibliographic_titles":[{"bibliographic_title":"Physical Review B - Condensed Matter and Materials Physics"},{"bibliographic_title":"Physical Review B - Condensed Matter and Materials Physics"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1103/PhysRevB.54.1194","subitem_relation_type_select":"DOI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1103/PhysRevB.59.13878","subitem_relation_type_select":"DOI"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-18"}],"displaytype":"simple","filename":"PhysRevB_54_1194.pdf","filesize":[{"value":"97.4 KB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2008141/files/PhysRevB_54_1194.pdf"},"version_id":"9b497d91-08fa-4d3f-8027-a73f4cf46a9a"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"19313"},"item_title":"Transition from magnetic to nonmagnetic ground state in a heavy-fermion compound Ce7Ni3 under high pressure","item_type_id":"40003","owner":"41","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2008141","relation_version_is_last":true,"title":["Transition from magnetic to nonmagnetic ground state in a heavy-fermion compound Ce7Ni3 under high pressure"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-22T03:15:03.334323+00:00"}
