Materials research is paused per mmoderwell (2026-06-18); Bias-Correction Protocol v2 fixes are deferred Bias-Correction Protocol v2. The Permanent Magnets Weekly Screening Check was deleted on 2026-08-01; no scheduled tasks remain.
The canonical RE-free permanent-magnet shortlist contains 250 candidates RE-free PM lab shortlist, parented to the RE-free permanent magnet candidates dataset. Saturation magnetization is the largest data gap: 22/24 Oliynyk candidates lack it RE-free PM candidates dataset.
The TCTP-TCSP screening pipeline combines relaxation, CHGNet magnetization/hull gates, DFT SCF, MAE, TB2J, Monte Carlo Tc, and comparison-post updates screening + DFT pipeline. Latest candidates include Fe₆B₂C₂Co₄ (predicted Tc ≈744 K), Fe₆B₄Ni₂Co₂ (≈592 K), and Co-free Fe₁₀B₄/Fe₁₀B₂C₂; MAE remains pending property screen. Fe₅W₁B₄Co₄ and Fe₆B₂C₂Ni₄ were packaged with cleaned CIFs and manifests; further P2/m rescreening was blocked by Modal failure Synthesis package v2.
Mn₃(BMo₂)₂ is a stable Cmmm ferromagnetic candidate: TB2J Tc ≈181 K, predicted Ms ≈0.232 T (≈0.453 T under 5% strain); coercivity is unmeasured magnetic-properties analysis, TB2J run.
Verified Fe₃P is tetragonal I-4 ferromagnetic, with Tc ≈705 K and Ms ≈0.99 MA/m; bulk anisotropy is unresolved verified-literature entry.
The Mn–Ge–N handoff separates measured Mn₃GeN evidence from the unverified Mn₁₂Ge₄N₃ hypothesis and includes experiment, deposition, protocol, CIF, and acceptance-rule artifacts experiment matrix, lab-deposit template, protocol note, measurement-ready handoff.
The Mn₅Ge₃+x verification slice closed successfully: validated 33-atom Mn₅Ge₃.₂₅ TB2J ordering, seven recorded claim outcomes, and no-reply outreach branch verification receipts ledger, high-pressure ordered cell, outreach quest.
The canonical measured-magnetic-data call requires cif_asset_id for every open item. Attachment routing and Gate 0 live-demo completion remain blocked by read_secret measured magnetic data call, Gate 0 route.
The mCGCNN service and ALIGNN comparison benchmark are complete mCGCNN service, benchmark post.
Corrected Co₃O₄ is Fd-3m with O x=0.389 corrected Co3O4 CIF. Nine spinel cases were retracted as overlapping-oxygen artifacts; perovskite cases remain valid correction comment.
DOE BES (Thomas Settersten, DE-FOA-0003600) is an actionable QMC/CC training-data sponsor; email sent 2026-07-24.

The Unified Outreach Tracker covers PMs, superconductors, electrolytes, thermoelectrics, and topological materials. Prospects include SandboxAQ, Simons MPS, Sloan, Renaissance/Open Source for Science Fund, Suhas Mahesh/Schmidt Sciences, ARPA-E MAGNITO, DCVC, and Paul Kent/ORNL.
Quest item IDs may contain malformed UUIDs missing the fourth hexadecimal segment.
Before publicizing computational results, perform explicit artifact-integrity checks—including CIF provenance, minimum interatomic distances, topology consistency, and comparison against controls—and retain correction/retraction receipts when a prior claim is invalidated.
Read complete communication threads and audit current platform assets before drafting or sending outreach.
Require target-specific artifacts, verified claim provenance, and sufficient measured-data support before personalized invitations.
For bounced or unverifiable contacts, mark CRM HOLD/blocked; independently verify delivery before any resend with a new idempotency key.
Paper-derived or measured-anchor leaderboard entries should preserve the experimental comparison: the MnFeCo₄Si₂ entry scored 75.3 while predicted Tc was 576.9 K versus measured 1039 K, demonstrating that leaderboard scores and individual predicted properties require calibration against measured anchors. MnFeCo₄Si₂ leaderboard entry
Mn₅Ge₃ analysis required correction of an initial exchange-sum/topology interpretation. After rebuilding a CIF-consistent 456-bond topology, Monte Carlo found no ferromagnetic or q=(0,1/2,0) long-range order, shifting the diagnostic focus to the underlying DFT SCF state; related outreach was paused until the corrected rerun and then sent with the correction. corrected analysis, topology rebuild
Leaderboard invitations are most credible when anchored to the recipient's specific candidate or measurement expertise and a concrete submission/critique request; after one allowed follow-up, CRM should remain quiet-unless-reply or stop-unless-reply. Recent outreach produced no external leaderboard submissions or replies, so future work should prioritize new-value additions rather than repeated nudges.
The RE-Free Permanent Magnet Leaderboard is live with a validated scoring route and internal calibration anchors; current examples include Cmcm Fe₂B at 91.6, Fe₁₂Sn at 91.7, LiFe₆Ga₄ at 69.9, tau-MnAl at 67.5, MnBi at 57.4, and paper-derived MnFeCo₄Si₂ at 75.3. Supply-chain HHI materially affects rankings, and tau-MnAl exposes a predicted-versus-experimental Tc calibration gap (453 K versus approximately 650 K). External submissions remain the key pending validation. leaderboard,
For MnBi₁₋ₓGeₓ, the verification did not reproduce the paper's reported Ge anisotropy enhancement: parent MnBi gave approximately +17.79 MJ/m³ while Mn₁₆Ge₃Bi₁₃ gave approximately +0.63 MJ/m³; Monte Carlo Tc was approximately 425–440 K for parent and approximately 450 K for the Ge-substituted structure, below the reported 750/780 K. The verification arc is publicly closed with no further direct outreach. verification post, result comment
Corrupted or invalid CIF/topology artifacts can produce false magnetic conclusions; minimum-distance/overlap and provenance preflight checks are mandatory before DFT, TB2J, Monte Carlo, or public claims. When corruption is discovered, retract and correct the public result, rebuild from a clean CIF, and pause dependent outreach. Relevant corrections: Mn₅Ge₃ corrected topology, NVPF claims correction, FeB₄ audit correction, and Cycle 15 correction.
Magnetic ML outputs are hypotheses, not validated performance. Use structure sanity checks, CHGNet magnetization/hull gates, DFT SCF, MAE, and TB2J; track SCF failures by composition. Do not treat high Monte Carlo Tc as validated permanent-magnet performance without anisotropy and exchange validation Co-Fe-N-Sn exploration, Al-C-Mn-Mo exploration.
Test imaginary-phonon candidates with controlled symmetry-breaking distortions and re-relaxation; validate FM claims with DFT-based TB2J.
Measured-magnetism outreach should be grounded in target-specific paper/structure artifacts and explicit sufficiency criteria. If exact-composition literature lacks ordering, anisotropy-field, or saturation data, record the blind spot and park outreach rather than presenting predictions as measurements.
Strong PM proposals convert quantified blind spots and candidate-specific measurement needs into priced, fundable quests with preregistered claims, paper-derived structures, confirm/falsify criteria, receipt status, and blocked/out-of-scope claims.
ALIGNN, mCGCNN, and CHGNet cannot reliably classify FM versus AFM from crystal structure alone benchmark dataset, analysis post.
Fe₃CuAs₂ K₁ discrepancies are provenance-dependent: 0.384 MJ/m³ is direct TB2J DFT+SOC; 1.18 MJ/m³ is structural-analog hf_K1_corrected magnet_dataset_clean.
MLIP symmetry benchmarking supports a symmetry-preservation metric for Matbench Discovery: tested L21 Heuslers/half-Heuslers passed; Li₆PS₅Cl F-43m was preserved only by CHGNet, while Orb v3 and MACE-MP collapsed to P1.
Periodic-CIF superconductivity screening should use connectivity, layer direction, and interlayer-gap evidence—not vacuum detection—and pass candidate CIF and hull-distance outputs from GGen Nb–Se–{X} GGen scout.
Reusable generative-model failure examples include the CrystaLLM Pmm2 trap, GPSK-05 P1 collapse, and five Laves C14 route failures; flow matching and MLIP magnetic-symmetry-collapse benchmarking provide relevant framing.
