The pressure dependence (0-1 GPa) of the basal-plane magnetic penetration depth (\\lambda_a), the penetration depth anisotropy (\\gamma=\\lambda_c/\\lambda_a) and the temperature dependence of 1/\\lambda_i^2 (i=a,c) were studied in single crystals. A strong decrease of \\lambda_a with pressure was observed, while \\gamma and \\lambda_i^2(0)/\\lambda_i^2(T) are pressure independent. A linear relationship between 1/\\lambda_a^2(270 mK) and Tc was also found. The large decrease "},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1212.1308","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"}
