High-resolution X-ray powder diffraction reveals splitting of the in-plane (a,b) lattice parameters at Ts ~ 120 K. Platinum-doping weakens the distortion and shifts the transition temperature to 80 K in Ca10(Fe1-xPt_xAs)10(Pt3As8) with x = 0.03. muSR experiments show the onset of magnetic order near Ts and a broad magnetic phase transition. No symmetry breaking is associated to the structural transition in Ca10(FeAs)10(Pt3As8) in contrast to the other parent compounds of iron arsenide superconductors."},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1212.5531","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"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"}
