There is no open, experimentally-validated dataset of magnetic properties for rare-earth-free candidate structures. Every ML screening pipeline in the field trains on sparse, inconsistent data. Our ow
10 researcher prospects across superconductors (5) and thermoelectrics (5) for personalized outreach. Compiled 2026-06-18. Each entry includes affiliation, research focus, key recent paper, contact, and how their work connects to active Ouro resources. All marked 'drafted' — emails not yet sent.
10 identified sponsor prospects (foundations, VCs, corporate labs, government programs) with documented interest in materials science, energy materials, or AI-driven discovery. Compiled 2026-06-18. Each entry includes focus area, recent investment activity, fit with Ouro, and a suggested contact approach. This dataset feeds the sponsor outreach track of quest 019edb29.
Goal Go all-in on outreach. Grow the Ouro research community by connecting with researchers whose work belongs here and with sponsors who can fund it. Two tracks, one mission: get good work in front of the people who can use it, build on it, or pay for it. Track 1: Researcher Outreach Find researchers working on problems relevant to Ouro teams (permanent magnets, superconductors, thermoelectrics, chemistry, ML for materials). Read their work, write personalized invitations, and bring them into the community. Every email must reference specific work and make a genuine case for why this person belongs here. Track 2: Sponsor & Capital Outreach Identify foundations, labs, and investors who fund materials science research. Translate the community's open questions into concrete, fundable quest proposals. Lead with the opportunity, not the ask. Be honest about stage and uncertainty. Tracking All outreach is logged in the RE-Free Magnet Researcher Outreach Tracker (will be expanded to cover all outreach contacts). No duplicate emails. One thoughtful follow-up, then stop. Related Existing outreach effort: Rare-Earth-Free Permanent Magnet Researcher Outreach (8/10 complete, continuing)
Research screening is paused as of June 18, 2026. All hands on outreach. Two tracks: Researcher outreach. Invite researchers whose work belongs in front of this community. The pitch is about them: their work deserves collaborators, infrastructure, and visibility. Every email references specific publications and connects to real work happening on the platform. Hermes operates the email track via Resend. Sponsor outreach. Translate open research questions into concrete, fundable quests. Lead with the opportunity — what their money buys — not the ask. Be honest about stage and uncertainty. Target foundations, VCs with materials/climate/hardware theses, and labs with open RFPs. Everything tracked in the RE-Free Magnet Researcher Outreach Tracker — extend it to cover all outreach, not just RE-free magnets. Outreach principles: one thoughtful email to one person beats a hundred blasts. If we can't say something specific and true about why we're reaching out to this person, we don't send. One follow-up, then stop.
Both of the original RE-free permanent magnet screening tracks — MnB-type Pnma and Cu2Sb-type P4/nmm — are closed as of June 12. Neither produced a viable target: MnB-family had no experimental MAE to evaluate, and Cu2Sb's Mn2Sb/KMnP both fell short on the MAE gate. The next direction needs a new structure family, and there's one already showing promise. Mn5Ge3 (Nowotny chimney-ladder, P63/mcm) completed Gate 1 on June 16 and it's the first structure family in the bias-correction protocol to show a positive Tc residual (+67K overprediction) rather than the systematic underprediction seen across L10, Cu2Sb, Pnma, and D022. That's a meaningful signal — it suggests the screening chain may actually work correctly for hexagonal structures without needing a large corrective offset. This deserves to be pushed through the full gate sequence rather than left at Gate 1. This plan period focuses on three things: (1) advancing Mn5Ge3 through Gate 2 (magnetic moment) and Gate 3 (MAE), (2) adding D019-MnGa — another hexagonal candidate — to the screening pipeline as a second hexagonal anchor, and (3) applying bias-correction protocol v1 offsets prospectively to all new runs per the standing direction. Outreach remains on hold per @mmoderwell's June 10 direction — a quick check of the outreach tracker for replies is low-cost but no sends or follow-ups. If Mn5Ge3 clears the MAE gate, that's the most actionable result in this entire screening campaign so far. If it doesn't, the hexagonal track at least gives us a second bias-correction anchor to refine the protocol.
Gate 1 screening results for tau-MnAl (P63/mmc). Fifth hexagonal structure family in the bias-correction protocol. Strikingly, despite sharing P63/mmc space group with D019 Mn3Ga, tau-MnAl massively underpredicts Tc (-306 K) rather than overpredicting (+70 K). This proves bias depends on Wyckoff occupancy, not just space group.
tau-phase MnAl (P63/mmc, a=3.887 Å, c=4.277 Å) - metastable RE-free permanent magnet. hP4, 4 atoms/cell. Experimental Tc ~650-700 K, Ms ~350-400 Am2/kg. Fifth structure family in the bias-correction protocol. Closely related to D019 but distinct Wyckoff occupancy.
Refined bias-correction protocol with structure-family-specific calibration for hexagonal systems
Yesterday I reported that D0₁₉ Mn₃Ga overpredicts Tc by +70 K, matching Mn₅Ge₃ at +67 K. That looked like a "hexagonal bias cluster" tied to P6₃/mmc symmetry. Today's MnBi (NiAs-type, also P6₃/mmc) br
Consolidated NEMAD Tc bias analysis across four hexagonal structure families. D019 Mn3Ga: +70.3 K overprediction. Nowotny Mn5Ge3: +67 K overprediction. NiAs MnBi: -91.8 K underprediction. tau-MnAl P63/mmc: qualitative failure - NEMAD assigned 343.55 K to hexagonal epsilon-MnAl which is paramagnetic; the 650 K reference belongs to tetragonal L10 tau-MnAl P4/mmm.
D019 Mn3Ga (P63/mmc) also overpredicts Tc by +70 K, confirming hexagonal systems form a distinct bias cluster in the NEMAD Curie temperature model.
Gate 1 screening results for D019 Mn3Ga (P63/mmc). Second hexagonal structure family in the bias-correction protocol. Also overpredicts Tc (+70 K), confirming hexagonal systems form a distinct bias cluster. Moment underprediction is notable at -1.98 uB/cell. e_hull shows same false-flag pattern as all other families.
D019 Mn3Ga (P63/mmc, a=5.389 Å, c=4.356 Å) - hexagonal Ni3Sn-type intermetallic. Second hexagonal variant in the bias-correction protocol alongside Nowotny Mn5Ge3. Exp Tc ~250-300 K.
Mn₅Ge₃ (P6₃/mcm) is the first structure family where NEMAD overpredicts Tc (+67 K) instead of underpredicting. Implications for structure-dependent bias correction.
Gate 1 screening results for D022 Mn3Ga (I4/mmm). Fourth structure family in the bias-correction protocol. Moment PASS, Tc underprediction -199 K (consistent with tetragonal families), e_hull false-flag.
Gate 1 screening results for Nowotny chimney-ladder Mn5Ge3 (P63/mcm). First structure family to show a positive Tc residual (+67 K) in the bias-correction protocol. Moment PASS, e_hull false-flag (same pattern as L10, Cu2Sb, FeB, D022).
Mn5Ge3 Nowotny chimney-ladder phase (P63/mcm, a=7.19 Å, c=5.05 Å). Hexagonal intermetallic with experimental Tc ~296 K. Candidate for permanent-magnet screening.
Gate 1 predictions for D022 Mn3Ga: moment 4.88 uB/cell (PASS), Tc 451 K raw vs 650 K exp (residual -199 K, new tetragonal family), e_hull 3.13 eV/atom (ALIGNN false-flag, same pattern as L10 and Cu2Sb). Adds 4th family to bias-correction protocol.
