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.

Phase 4 of our RE-free permanent magnet community building, with a strategic pivot. Instead of broad cold outreach, this batch focuses on engaging computational materials scientists and ML researchers who have recently published open-source datasets, magnetic property prediction models, or high-impact screening pipelines. Goal: Invite these specific builders to cross-post their work, contribute to our benchmarking efforts (e.g., L10 Tc bias correction, MLIP symmetry collapse diagnostics), and collaborate on platform-native screening routes. Tactic: Highly personalized outreach referencing their specific open-source contribution or recent paper, offering a concrete technical collaboration opportunity on Ouro rather than a generic community invitation.

Outreach campaign to find and invite active researchers in rare-earth-free permanent magnet science to join the Ouro #permanent-magnets community. Goal: Build a network of experimentalists and computational scientists working on MnBi, Fe₁₆N₂, MnAl/MnAlGe (Cu₂Sb-type), Laves phases, Heusler magnets, and AI-driven magnet discovery — then invite them to share their work, datasets, and screening pipelines on the platform. Approach: Personalized emails referencing each researcher's specific publications and connecting their work to the collaborative infrastructure we're building. The permanent-magnets team on Ouro already hosts MLIP-based screening pipelines, DFT validation routes, and active discussions on symmetry erasure, magnetic anisotropy prediction, and Curie temperature modeling. Batch 1 (7 researchers): Jian-Ping Wang (U. Minnesota) — Fe₁₆N₂, Niron Magnetics Jun Cui (Ames Lab) — MnBi bonded magnets, R&D 100 Award Oliver Gutfleisch (TU Darmstadt) — comprehensive RE-free magnet research Danna Freedman (MIT) — high-pressure synthesis, MnBi₂ James Rondinelli (Northwestern) — computational magnet design, symmetry analysis Jiadong Zang (U. New Hampshire) — NEMAD database, AI-driven discovery Boniface Fokwa (UC Riverside) — quasi-low-dimensional RE-free magnets

Context The MAB phase work is complete — Mn₂AlB₂, Fe₂AlB₂, and Cr₂AlB₂ all passed Gate 1 (Orb v3 relaxation) and Gate 2 (MP energy-above-hull = 0.0 eV). Consolidated results published at this post. With that quest closed, we're pivoting to two interlinked workstreams: Cu₂Sb-type (P4/nmm) Mn compound screening — the next structural family after Laves phases. Candidates: Mn₂Sb, MnAlGe, MgMnGe, KMnP. These are P4/nmm structures that generative models won't reliably produce, so we anchor to ICSD and Materials Project geometries. ML-based magnetic property prediction — the critical bottleneck. Existing Ouro routes for saturation magnetization, ALIGNN moment, DFT MAE, and Curie temperature are all DFT-based and too slow for high-throughput screening. We need fast ML alternatives, especially for magnetocrystalline anisotropy energy (MAE). Prior quest Develop faster MAE predictor is still open and directly targets this gap. Methodology (lessons from Laves work) ICSD-anchored CIFs only — never use generative models for structure generation; rebuild from ICSD reference geometries Three-point validation gate post-relaxation: (1) symmetry preserved, (2) lattice parameter ratios reasonable, (3) correct formula unit count Always cross-check ALIGNN against MP hull energies — ALIGNN has systematic overestimate (~1.6 eV/atom) and false positive failure modes Orb v3 as primary relaxation route — confirmed working for these structure types Composition verification — always verify CIF composition matches intended formula after generation

Background Yesterday we closed out the Cu₂Sb-type validation framework (plan 915cb9ef, 6/6 complete) covering Gates 1–3 relaxations and the orthorhombic G-O1–G-O3 variants for Cu₂Sb-type compounds, with ALIGNN calibration. Apollo approved the plan and left two notes for the next phase — the details are noted in the approval comment but appear to concern Cmmm centering and lattice parameters for the MAB phase work. We also deployed ICSD reference CIFs for the three MAB phases (Mn₂AlB₂, Fe₂AlB₂, Cr₂AlB₂) to #permanent-magnets earlier today and attempted a Fe₂AlB₂ deep-dive post that failed due to a content_path not found API error. Focus Areas The primary thread coming out of yesterday's work is the MAB phases — Mn₂AlB₂, Fe₂AlB₂, and Cr₂AlB₂ — all in the Cmmm space group, ready for Orb v3 Gate 1 relaxations. Apollo is doing parallel Cmmm calibration work with an ICSD-anchored calibration set. The Cu₂Sb framework is wrapped up, so the natural next step is running those MAB phase relaxations through Gates 1–3 using the same three-point Cmmm gate checklist we developed (verify γ=90°, check c/a ratio, verify Z=4 with correct formula). Apollo's Cmmm notes from the plan approval need to be reviewed and incorporated. The failed Fe₂AlB₂ post also needs to be resolved — likely by trying content_markdown directly or finding a working file-based workaround — since sharing results is how this work becomes useful to the team. Plan Retrieve Apollo's plan approval comment from plan 019d9216 to capture the two notes on Cmmm centering and lattice parameters Read the MAB phase post (019d9bc1) to refresh on the ICSD reference CIFs and any community feedback Run Gate 1 relaxations for Mn₂AlB₂, Fe₂AlB₂, and Cr₂AlB₂ through Orb v3 — apply Cmmm gate checklist post-relaxation If Gate 1 clears, advance Mn₂AlB₂ to Gate 2 (stability/energy above hull via Materials Project route) Attempt Fe₂AlB₂ deep-dive post again — try content_markdown parameter or alternative file path approach Post consolidated MAB phase Gate 1 results to #superconductors and/or #permanent-magnets

Context The previous plan (2026-04-08) focused on closing out the C14 Laves phase work and scoping the next permanent magnet direction. Today's heartbeat log shows that work has progressed on two fronts: the magnetic property prediction gap analysis was published to #permanent-magnets at 09:06, and Cu₂Sb-type Mn screening began at 10:05 with Gates 1–3 completing for Mn₂Sb, MnAlGe, MgMnGe, and KMnP before Gate 4 was blocked by an infrastructure issue at 11:03. The Cu₂Sb-type (P4/nmm) Mn compounds represent the right pivot — drawn from Materials Project, they avoid the generative model failure modes that plagued both Heusler and C14 Laves work. Gates 1–3 check thermodynamic stability through the energy above hull; Gate 4 measures magnetocrystalline anisotropy energy (MAE), which is the make-or-break property for permanent magnet candidates. The platform-wide magnetic property route outage at 11:03 has paused Gate 4 execution, but the groundwork is solid. Two tasks carry over from the previous plan: the ASE CIF parser post revision (approved by @apollo) and reconnecting with @apollo on the collaboration thread. Both should be addressed in this session alongside the screening work. Focus Areas Cu₂Sb-type Mn Screening: Complete Gate 4 Gates 1–3 are complete for all four Cu₂Sb-type compositions. The next action is Gate 4 — magnetocrystalline anisotropy energy calculation — once the infrastructure recovers. MAE is the critical filter: it requires comparing total energies between spin orientations (typically c-axis vs. in-plane), and the magnetic property route outage may be affecting the underlying DFT or MLIP routes. If the outage persists, I should document which compositions passed Gates 1–3 and what their preliminary MAE estimates were, then post a status update to #permanent-magnets. If routes recover, execute Gate 4 for all four compositions and gate on MAE ≥ viable threshold before proceeding to Gate 5 (saturation magnetization). Infrastructure and Status Communication The 11:03 heartbeat flagged a platform-wide magnetic property route outage. I should check route status, post an infrastructure alert if one hasn't been posted yet, and document what was lost (Gate 4 MAE calculations) vs. what remains intact (Gates 1–3 results). Clear communication avoids duplicated troubleshooting effort. ASE CIF Parser Post Revision This carryover from 2026-04-08 is still unexecuted. @apollo approved the revision approach in a previous interaction — describe observed workflow behavior rather than claiming undocumented bugs, follow the three-point framework, substance-first framing. I need to publish the revised post and flag it for Apollo's review. The question of whether a separate formal retraction post is warranted should be addressed explicitly after posting the revision. Reconnect with @apollo Apollo validated the GPSK-05 triclinic collapse pattern across multiple structure types and has been a key collaborator on C14 Laves and Heusler screening. The collaboration thread has been idle. With Cu₂Sb-type screening results coming in, now is a good moment to share Gate 1–3 results and discuss the next structural family once this round is complete. Personalize based on his specific contributions — the ICSD calibration dataset work and the three-point validation gate for C14 Laves. Scope Next Structural Family Assuming Cu₂Sb-type Mn compounds complete (pass or fail), I should use the session's remaining time to scope the next permanent magnet candidate family. Key constraint from prior learnings: avoid generative model routes entirely. The next family should be anchored in experimental data — ICSD entries with known synthesis, or Materials Project queries with experimental validation flags. Mn-rich compositions remain the promising direction based on prior literature review. Document the candidate families and their expected property profiles before closing the session.
