The derivatives of the temperature dependence of both magnetic and nematic susceptibilities show clearly sharp peak when the transitions are first-order. Accordingly, we show that while both of the magnetic and nematic transitions change from first-order to second-order with increasing Barium doping level, there is a narrow doping range where the former becomes second-order but the l","authors_text":"Dongliang Gong, Huiqian Luo, Shiliang Li, Tao Xie, Xiaoyan Ma, Yanhong Gu, Yi-feng Yang, Zhaoyu Liu","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2017-05-14T09:16:07Z","title":"Nature of the Antiferromagnetic and Nematic Transitions in Sr$_{1-x}$Ba$_x$Fe$_{1.97}$Ni$_{0.03}$As$_2$"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1705.04938","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":"sha256:505afaf983d2316bfbaad84fe3aa434747ec21885e7166be1ffc303e8a8f84e4","target":"record","created_at":"2026-05-18T00:33:06Z","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":"6591ad933d4dfc36c78dc1c42414a40bf8ff9752b7ea485f78517b8e2f02493f","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2017-05-14T09:16:07Z","title_canon_sha256":"0958030a537d6d02fe5327858085474f84032afd01d208e020003240c58f4cbe"},"schema_version":"1.0","source":{"id":"1705.04938","kind":"arxiv","version":2}},"canonical_sha256":"7b00b58432e4cb86606cb7328606b2f2de6a2512a988edf4c0b6c31039a00cbb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7b00b58432e4cb86606cb7328606b2f2de6a2512a988edf4c0b6c31039a00cbb","first_computed_at":"2026-05-18T00:33:06.595600Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:33:06.595600Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"h2cRBTsEmU+AEeZpE5EMChUPTbTd1R8lI5ymDhZY0InNlDfQbaYxqqeR2cBDuqrnHr7rs/3Wnb4C79dOSwH2AQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:33:06.596326Z","signed_message":"canonical_sha256_bytes"},"source_id":"1705.04938","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:505afaf983d2316bfbaad84fe3aa434747ec21885e7166be1ffc303e8a8f84e4","sha256:d1ae619929589d382be9583a73932efd2a4e0f0ab51d3822866d124f67568a4f"],"state_sha256":"aa447e461155ff5a1e2fdbc6d8b9e7344f9a6221ed4190416eaa11fe7e8c4e0c"}
