In SmCoAsO, the large MR effect is also observed up to the Curie temperature $T_\\mathrm{C}$, and it is found to be originating in the presence of another antiferromagnetic phase in the low-magnetic field region of the ferromagnetic phase.","authors_text":"Chishiro Michioka, Hiroto Ohta, Kazuyoshi Yoshimura","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2011-09-13T10:07:16Z","title":"Large Magnetoresistance Effects in $Ln$CoAsO with a Ferromagnetic-Antiferromagnetic Transition"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1109.2730","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:94bc93c85f8142b5045203c43a6e749fe5e4bcb87b184cef473defaea72ad545","target":"record","created_at":"2026-05-18T02:21:36Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"c8a0bf46853ab799ca44a182474aed8c901d9cc8455a6e0b1d9d2bbfaae0a37a","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2011-09-13T10:07:16Z","title_canon_sha256":"c9d10ac587fbec0d65d183d48485ee5821c9a4e9667651856e007bae2a2d2e8b"},"schema_version":"1.0","source":{"id":"1109.2730","kind":"arxiv","version":2}},"canonical_sha256":"9046cccbe25dd8fc7bcf998e5bf628edc67dbef7e5254bb73318009ab6512e70","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9046cccbe25dd8fc7bcf998e5bf628edc67dbef7e5254bb73318009ab6512e70","first_computed_at":"2026-05-18T02:21:36.780373Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:21:36.780373Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"pguXB6d82sLLThgSFtIb+K0xtcEMX3Escqcr7yem4r4zOx+b3NvZrx91ng4j0II+kFjjhBu/aHhuVRnNKvGVCA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:21:36.780754Z","signed_message":"canonical_sha256_bytes"},"source_id":"1109.2730","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:94bc93c85f8142b5045203c43a6e749fe5e4bcb87b184cef473defaea72ad545","sha256:9e335e13022fe5811c060218d3b1d53be8c08f76d7c4df866740a3037f8e03da"],"state_sha256":"821b09692cea214e36e0ed364b12eb80cf6a5b312eb530914eade2733cf87cda"}
