It is confirmed that this compound orders antiferromagnetically at TN=4.4 K, while ρ(T) shows no anomaly at TN but a sharp peak at Tρ=6.1 K. Below Tρ, M/B rises suddenly for B∥c, the easy magnetization axis, suggesting the onset of a short-range ferromagnetic order. At 2 K, M(B∥c) shows a metamagnetic transition at a small field of 0.06 T from the antiferromagnetic ground state to a field-induced ferromagnetic state. The peak in C(T) shifts from 4.3 K in zero field to 4.0 K in B∥C=0.1 T, and furthermore a shoulder appears at 4.3 K. With increasing magnetic field, the shoulder changes to a broadened maximum, which shifts towards higher temperatures. These observations indicate that the ferromagnetic interaction competes with the antiferromagnetic one even in zero field. A large negative magnetoresistance, MR=[ρ(B)-ρ(0)]/ρ(0), was observed in the vicinity of Tρ. For I∥c, the MR amounts to -25% at 3 T for B∥c, which is twice that for B⊥c. The large MR for I∥B∥c is a result of the increase of the c-axis conduction in the field-induced ferromagnetic alignment of Ce spins. However, the MR for I⊥c is essentially the same for B∥c and B⊥c, suggesting the confinement of carriers within the Te sheet sandwiched by the ferromagnetically coupled CeTe layers.","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":"11 609"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2000-11-01","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"17","bibliographicPageEnd":"11 613","bibliographicPageStart":"11 609","bibliographicVolumeNumber":"62","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.62.11609","subitem_relation_type_select":"DOI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1103/PhysRevB.57.5025","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_62_11609.pdf","filesize":[{"value":"120.9 KB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2008186/files/PhysRevB_62_11609.pdf"},"version_id":"d56425e4-9f5b-4bd5-9e70-b72fd3c387fe"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"19286"},"item_title":"Competing interactions and anisotropic magnetoresistance in layered CeTe2","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":"2008186","relation_version_is_last":true,"title":["Competing interactions and anisotropic magnetoresistance in layered CeTe2"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-22T03:19:04.257645+00:00"}
