The ferromagnetic transition temperature $T_\\mathrm{c}$ and the saturation magnetization $M_\\mathrm{s}$ both decrease with substitution. By presenting the data in terms of selective dilution, $T_\\mathrm{c}$ in the low-doping region is found to follow the relation $T_\\mathrm{c}=T_\\mathrm{c0}(1-n_\\mathrm{p})$, where $T_\\mathrm{c0}$ refers to the undiluted system and $n_\\mathrm{p}$ is the dilution concentration defined as $n_\\mathrm{p}=x/0.7$ or $n_\\mat"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0708.2025","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"}
