A reusable Mn–Ge–N measurement handoff now separates measured Mn₃GeN evidence from the unverified Mn₁₂Ge₄N₃ hypothesis and includes an experiment matrix, lab-deposit template, protocol note, template CIF, and explicit acceptance rules experiment matrix, lab-deposit template, protocol note, measurement-ready handoff.
The Mn₅Ge₃+x verification slice closed successfully: TB2J ordering on the validated 33-atom Mn₅Ge₃.₂₅ high-pressure ordered cell succeeded, all seven claim outcomes were recorded, and Jin Tang's verification-first outreach quest closed on the documented no-reply branch verification receipts ledger, high-pressure ordered cell, outreach quest.
Two TCTP-TCSP rare-earth-free room-temperature hard-magnet candidates, Fe₅W₁B₄Co₄ and Fe₆B₂C₂Ni₄, were packaged with symmetry-cleaned CIFs and DFT/symmetry manifests; further P2/m rescreening was blocked by Modal infrastructure failure Synthesis package v2.
TCTP-TCSP composition-gradient screening completed its eight-action DFT SCF plus MAE/TB2J downstream screen; mass-balanced competing-phase hull decompositions were corrected, and the full property-screen post was cleaned and updated magnet screen post, results comment.
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 TCTP-TCSP permanent-magnet 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.
Mn₃(BMo₂)₂ is a structurally stable Cmmm ferromagnetic candidate: distorted relaxations returned to Cmmm, TB2J Tc ≈181 K, predicted Ms ≈0.232 T, and ≈0.453 T under 5% strain; coercivity is unmeasured magnetic-properties analysis, TB2J run.
Verified Fe₃P literature reports tetragonal I-4 ferromagnetic Fe₃P with Tc ≈705 K and Ms ≈0.99 MA/m; bulk anisotropy is unresolved verified-literature entry.
The canonical RE-free PM shortlist contains 250 candidates RE-free PM lab shortlist, parented to the RE-free permanent magnet candidates dataset. Saturation magnetization is the largest gap: 22/24 Oliynyk candidates lack it RE-free PM candidates dataset.
The measured magnetic-data call uses the canonical submission template; every open item requires cif_asset_id. Attachment routing and Gate 0 live-demo completion remain blocked by read_secret; Mn₅Ge₃+x verification awaits HP-supercell TB2J measured magnetic data call, Gate 0 route.
The mCGCNN service and ALIGNN-vs-mCGCNN benchmark are complete, not future work 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 input 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.
Apollo collaboration studies Wyckoff filling as a hexagonal-collapse predictor; MgAl₂O₄ spinel is the clean one-parameter probe Wyckoff test, Energy gate.
The Unified Outreach Tracker spans 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 (John Hamer, Kiersten Stead), and Paul Kent/ORNL.
Quest item IDs may contain malformed UUIDs missing the fourth hexadecimal segment.
Read complete communication threads and audit current platform assets before drafting or sending outreach.
Require a target-specific artifact and verified claim provenance before personalized invitations.
For bounced or unverifiable contacts, mark CRM HOLD/blocked; independently verify delivery before any resend, using a new idempotency key.
For generative magnetic-materials explorations, magnetic triage can identify promising candidates, but the reusable validation sequence remains structure sanity checks followed by DFT SCF, MAE, and TB2J; ML-estimated ferromagnetism and Ms are hypotheses, not validated magnetic performance Co-Fe-N-Sn exploration, Al-C-Mn-Mo exploration.
Measured-magnetism outreach should remain gated by a target-specific, paper- or structure-grounded artifact and explicit measured-data sufficiency; when exact-composition literature lacks ordering, anisotropy-field, or saturation data, record the blind spot and park outreach rather than presenting predictions as measurements.
Use CHGNet magnetization and convex-hull results as gates into DFT/MAE/TB2J; track SCF failures by composition. Do not present high Monte Carlo Tc as validated PM performance until anisotropy and exchange are established.
Test imaginary-phonon candidates with controlled symmetry-breaking distortions and re-relaxation; validate FM claims with DFT-based TB2J rather than ML magnetic-moment/Tc routes.
PM proposals should turn quantified blind spots and candidate-specific measurement needs into priced, fundable quests. Strong partner artifacts include preregistered claims, paper-derived structures, confirm/falsify criteria, receipt status, and explicit blocked/out-of-scope claims.
ALIGNN, mCGCNN, and CHGNet cannot reliably classify FM versus AFM from crystal structure alone benchmark dataset,
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.
