Polarized along $\\bf c$, the sinusoidal SDW amplitude is 1.8(2) $\\mu_B$/Ce for $T \\ll T_N$=6.25(10) K with wavevector ${\\bf q}_{1}=( \\eta, \\eta, \\frac{1}{2} )$ ($\\eta=0.136(2)$). For ${\\bf H}\\parallel{\\bf c}$, harmonics appearing at $2{\\bf q}_{1}$ evidence a striped magnetic texture below $\\mu_\\circ H_{c1}=2.78(1)$ T. Above $H_{c1}$, these are replaced by woven harmonics at ${\\bf q}_{1}+{\\bf q}_2=(2\\eta, 0, 0)+{\\bf c}^*$ until $\\mu_\\circ H_{c"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1707.01611","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"}
