Next follow-up wave for all outreach contacts is ~2026-07-09. CRM has ~60 rows across 51 sent / 3 replied / 6 blocked statuses. Key replied researchers: Suhas Mahesh (Schmidt Sciences, QMC pilot with Kent), Magdau (declined).
ARPA-E MAGNITO program is 20M). Snyder is now at ARPA-E directly. ARPA-E and BEV sponsor outreach emails both confirmed delivered 2026-06-19 (email_ids 309060e9 and 509a6a45). DCVC contact: John Hamer ([email protected]) and Kiersten Stead ([email protected]) for follow-up.
Rogl (Univ. Vienna) warmly referred to Jose J. Plata Ramos ([email protected], Univ. Seville) as supervisor who can authorize hosting DL-skutterudite zT model on Ouro. Plata outreach email sent 2026-06-24 (d5f6b0b4). Rogl thank-you sent.
Materials research is paused per mmoderwell direction (2026-06-18). Bias-Correction Protocol v2 fixes (Mn5Ge3 ±15-20K uncertainty band, MnBi 630K Chen et al. source, post table reconciliation to dataset ground-truth 362.8K not 467K) are deferred until materials work resumes. Bias-Correction Protocol v2
Generative model failure catalog used as reusable outreach anchor: CrystaLLM Pmm2 trap, GPSK-05 P1 collapse, 5 Laves C14 route failures. Martiniani (NYU, flow matching) pitch framed continuous denoising as escape from discrete space-group traps; Bussy (EPFL) and Tian Xie (Microsoft, MatterGen) pitches framed as MLIP magnetic symmetry collapse benchmark.
Corrected researcher contacts discovered during outreach: Tian Xie → [email protected] (Microsoft Research, not Merck); Matthew McDermott → [email protected] (Newfound Materials CEO, not MIT); Philipp Benner → MACE-JAX gmail address; Kin Fai Mak → [email protected] (MPSD Hamburg, not Cornell); Iek Chen [email protected] invalid with no discoverable alternative. Gutfleisch and Di Xiao ([email protected]) follow-ups also bounced.
FeB is 16 meV/atom above the convex hull (metastable/synthesizable) and the optimal target in the (Mn,Fe)B and (Cr,Mn)B Pnma series, where Tc has a non-monotonic minimum at x=0.25 (Mn,Fe)B and (Cr,Mn)B Pnma solid-solution sweep post. CrB lacks a Pnma ground state (true is I4_1/amd), confirming its Gate 2 failure is chemistry-driven MnB-type FeB monoboride screening post.
The canonical permanent magnet team URL is https://ouro.foundation/teams/permanent-magnets memory anchor post. Key RE-free researchers include Felser, Eriksson, Salazar, Alice & Bob, and Jiadong Zang rare-earth-free permanent magnet outreach quest, post.
The Calculate energy above the convex hull route throws a server-side TypeError for MnB-type structures; fallback to Search Materials Project Calculate energy above the convex hull. Route d040d3b6 provides non-Orb MLIP relaxers (e.g., CHGNet) but lacks per-atom forces post, comment.
C14 Laves phases feature coupled c/a ratios and z(4f) internal coordinates comment. SmCo₅ has zero free Wyckoff sites, making it uninformative for symmetry erasure studies comment.
For Ouro datasets, use upsert with partial rows instead of update_dataset with overwrite (which rejects NaNs); query_dataset is strictly SELECT-only and case-sensitive.
Always use sign-sensitive magnetic moment columns in benchmark datasets to capture ML sign reversals (e.g., CHGNet's ~6× FM/FiM reversal in Mn₂Sb) post.
Sanitize ICSD magnetic moment data via measurement-method keyword filtering to remove mixed criteria entries post.
Employ magnetic space group pre-filtering (e.g., GPSK-05) to eliminate compute waste in MLIP permanent magnet screening infrastructure feedback comment.
CRM schema drift: columns like 'category', 'notes', 'researcher_last' no longer exist in the Unified Outreach Tracker. Use get_asset + individual row upserts instead of query_dataset for CRM reads/writes to avoid schema errors.
Tavily API can be blocked (HTTP 432) for extended periods (12+ consecutive ticks). When blocked, manual stdlib scraping of institutional profile/directory URLs is a poor fallback for contact email lookup (zero hits across 8+ URLs tested). Tavily quality also degrades for email lookups even when restored (returns irrelevant directory results). Plan outreach research for periods when Tavily is confirmed working.
The Unified Outreach Tracker CRM dataset is prone to NaN corruption that causes all update_dataset and individual row upsert calls to fail with 'Out of range float values'. Fix: rebuild the dataset by removing stale/duplicate/test rows (e.g., reduced from 73→56 rows on 2026-06-24). This corruption recurs periodically and must be cleaned before CRM work can proceed.
MLIP Symmetry Erasure: Operates via independent mechanisms: interlayer registry collapse (non-magnetic WSe₂ WSe₂ discriminator post) and magnetic symmetry erasure. In C14 Laves phases, Wyckoff occupancy drives collapse (Ti-4f/Fe-6h safe; Fe-2d triggers collapse), superseding composition hypotheses TiFeSi C14 discriminator results. Diamagnetic C14 MgZn₂ rules out magnetism as the root P1 collapse cause post. Platform CIFs may lose symmetry pre-relaxation (e.g., Mn₂Sb P4/nmm→Pm comment), and Mn₂Sb negative controls involve antiparallel Wyckoff sites file. Orb v3 inherits P1 triclinic collapse, making negative formation energies unreliable for magnetic intermetallics post.
Model Biases & Uncertainties: ALIGNN-OSZICAR shows ~2.4-2.7 eV/atom e_hull bias for binary borides (ordering preserved) and ~2.0 eV/atom formation energy overestimate for PMs, plus unreliable moments file. Model-choice uncertainty envelopes are ±0.25 eV/atom with a ~0.47 eV/atom systematic offset and ±0.05 eV/atom modulation per structure type comment. Sign reversals between JARVIS/MP confirm composition-dependent reference-state energetics as the dominant confound, ruling out coordination-number averaging comment. Curie temperature is the most tractable ML target for PMs (NEMAD R²=0.92), while MAE is the hardest gap.
Screening & Infrastructure: RE-free PM Curie temperature screening requires multi-anchor bias-correction (e.g., -423K for L10) to prevent false negatives. tb2j reliably filters uniaxial anisotropy direction but under-predicts quantitative K1/MAE for L10 itinerant magnets τ-MnAl L10 calibration post. pymatgen.symmetry.analyzer is sandbox-blocked, preventing symmetrization workflows post.
