Common behavior is observed for three FM layers, where the additional relaxation obeys both a strict inverse power law dependence $\\Delta G =K \\:t^{n}$, $n=-\\textrm{1.04}\\pm\\textrm{0.06}$ and a similar magnitude $K=\\textrm{224}\\pm\\textrm{40 Mhz}\\cdot\\textrm{nm}$. As the tested FM layers span an order of magnitude in spin diffusion length $\\lambda_{SDL}$, the results are in support of spin diff"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1011.5868","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"}
