The absolute values of \\lambda, the Ginzburg-Landau parameter \\kappa, the first H_{c1} and the second H_{c2} critical fields at T=0 are \\lambda(0)=720(100)nm, \\kappa(0)=55(9), \\mu_0H_{c1}(0)=1.8(3)mT, and \\mu_0H_{c2}(0)=1.9(2)T. The zero temperature value of the superconducting energy gap \\Delta(0) was found to be 0.35(1)meV corresponding to the ratio 2\\Delta(0)/k_BT_c=3.83(10). At low temperatures \\lambda^{-2}(T) saturates and becomes constant be"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0905.3906","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"}
