Imaging of the spatial distribution of electric-field-induced optical rotation reveals that the single crystals preferentially form single ferroaxial (FA) domains. Magnetization and neutron diffraction measurements show that Mn$^{2+}$ and Ni$^{2+}$ magnetic moments order antiferromagnetic"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"Single crystals preferentially form single ferroaxial domains; all independent magnetoelectric tensor components allowed by the magnetic point group 6/m' are detected, with the chi33 component exhibiting a pronounced temperature-dependent anomaly including a peak and sign reversal at TN = 83 K.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"That the observed single-domain preference and chi33 anomaly are intrinsic to the ferroaxial structural framework and remain robust under Sr-Pb substitution, without significant influence from growth-induced defects or measurement artifacts.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"Single crystals of SrMn2Ni6Te3O18 form single ferroaxial domains and show antiferromagnetic order at 83 K with all allowed magnetoelectric tensor components detected, including a temperature anomaly in the chi33 component.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"Single crystals of SrMn2Ni6Te3O18 preferentially form single ferroaxial domains and show all symmetry-allowed magnetoelectric responses with a chi33 anomaly at the 83 K transition.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"cab4eba48332f70a7f960fd7ef9412873d16dd2837755674711ccca0b56e0543"},"source":{"id":"2604.21460","kind":"arxiv","version":2},"verdict":{"id":"c7c04de2-38c4-421a-ba6e-5e50ad5fa4b6","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-09T21:26:47.183137Z","strongest_claim":"Single crystals preferentially form single ferroaxial domains; all independent magnetoelectric tensor components allowed by the magnetic point group 6/m' are detected, with the chi33 component exhibiting a pronounced temperature-dependent anomaly including a peak and sign reversal at TN = 83 K.","one_line_summary":"Single crystals of SrMn2Ni6Te3O18 form single ferroaxial domains and show antiferromagnetic order at 83 K with all allowed magnetoelectric tensor components detected, including a temperature anomaly in the chi33 component.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"That the observed single-domain preference and chi33 anomaly are intrinsic to the ferroaxial structural framework and remain robust under Sr-Pb substitution, without significant influence from growth-induced defects or measurement artifacts.","pith_extraction_headline":"Single crystals of SrMn2Ni6Te3O18 preferentially form single ferroaxial domains and show all symmetry-allowed magnetoelectric responses with a chi33 anomaly at the 83 K transition."},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2604.21460/integrity.json","findings":[],"available":true,"detectors_run":[{"name":"ai_meta_artifact","ran_at":"2026-05-21T12:41:36.721351Z","status":"completed","version":"1.0.0","findings_count":0},{"name":"doi_compliance","ran_at":"2026-05-20T00:57:24.023616Z","status":"completed","version":"1.0.0","findings_count":0}],"snapshot_sha256":"08dc01cf72d0e1b309096df8ea431dc26a62da41e81fa700b051f481d69b1433"},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
