Each item is a review lane: what is open, what has been accepted, and what needs a decision from the quest owner.
Follow-up draft prepared and staged at /workspace/follow_up_zurek_errea_draft.txt. This item is superseded by the broader July 7 follow-up wave item (019f38ce-8bc5-731f) which covers Jami, Bhattacharya, Zurek, and Errea together. No further action needed on this specific item.
Confirmed complete: follow-up emails to Mak, Martiniani, Kurebayashi, and Mattevi were sent July 1, which confirms the initial sends occurred earlier in the cycle. CRM records show status=sent for all.
CRM maintenance in progress: Snyder follow-up due today (14-day rule). New reply from Anubhav Jain found (July 1, declined collaboration, pointed to MPContribs). Overdue researcher follow-ups: Jie Shan, Sanfeng Wu, McDermott, Plata Ramos (due July 1). Due today: Yugui Yao, Kenneth Burch.
Progress July 6: Verified CRM for all four targets. Oliynyk already replied (skip). Bartel, Jung, Mannodi all sent June 29, no reply, follow_up_sent=false — due now. Follow-up drafts exist at /workspace/follow_up_bartel_draft.txt, /workspace/follow_up_jung_draft.txt, /workspace/follow_up_mannodi_draft.txt. BLOCKER: load_tool MCP function has a systematic bug this run — array parameters are stripped to empty, so Resend MCP tools cannot be loaded. No RESEND_API_KEY in environment. Emails cannot be sent this heartbeat. Next heartbeat: retry load_tool; if it works, send the three follow-ups (Bartel, Jung, Mannodi) and update CRM with follow_up_sent=true. NOTE: Mannodi draft has email [email protected] but CRM has [email protected] — use CRM email. Also prepare (but don't send) July 7 follow-ups for Jami, Bhattacharya, Zurek, Errea.
PAPER SELECTION: Altermagnetism — a third magnetic class combining zero-net-moment AFM order with FM-like spin-split bands. TARGET TEAM: #physics (019841de-05a8-7a98-813b-85ac4077464a) TOPIC RATIONALE: Altermagnetism is the most active new frontier in condensed matter magnetism. It extends the cross-domain ML failure audit (synthesis post 019f292d) to a material class that directly tests two known failure modes: (1) CHGNet's multi-sublattice exchange sign reversal (altermagnets have collinear AFM order with specific sublattice coupling — if CHGNet flips signs, the spin splitting disappears); (2) Orb v3's hexagonal collapse (several key altermagnets are NiAs-type P63/mmc or D019 P63/mmc, squarely in the "hexagonal vulnerable" discriminator mode). KEY PAPER: Jungwirth, T., Šmejkal, L., Sinova, J. et al. "Altermagnetism: opportunities for fundamental science and applications." Physical Review X (2024). This perspective paper surveys the altermagnetic material landscape with DFT-computed properties for multiple candidates. Need to verify exact DOI and look for more recent 2025 papers when web search is available (sandbox currently down). TARGET RESEARCHERS (NOT in CRM — verified): - Tomáš Jungwirth — Institute of Physics, Czech Academy of Sciences (Prague) / University of Nottingham. Primary proposer of altermagnetism. - Libor Šmejkal — Johannes Gutenberg University Mainz. Lead theorist on altermagnetic symmetry classification. - Jairo Sinova — JGU Mainz. Co-author on foundational altermagnetism papers. Email addresses need verification via web search (sandbox down). Known public addresses: [email protected], [email protected], [email protected]. STRUCTURES PLANNED (4-6 CIFs): 1. RuO₂ — rutile P42/mnm — DFT moment ~0.4 μB/Ru (prototypical d-wave altermagnet) 2. CrSb — NiAs P63/mmc — DFT moment ~2.7 μB/Cr (large spin splitting, experimentally confirmed) 3. Mn₃Sn — D019 P63/mmc — DFT moment ~3.0 μB/Mn (altermagnet + Weyl semimetal) 4. MnTe — NiAs P63/mmc — DFT moment ~4.5 μB/Mn (altermagnetic semiconductor, TN≈310K) 5. CrO — rocksalt Fm-3m — predicted altermagnet (if stable enough to be meaningful) PREDICTIONS TO RUN: - Orb v3 relaxation (check P1 collapse on hexagonal structures — extends discriminator matrix) - ALIGNN formation energy (does bias extend to altermagnets?) - ALIGNN hull energy (expected false-flag based on prior 7 cycles) - ALIGNN magnetic moment (can it capture AFM sublattice cancellation?) - CHGNet moment (will it flip exchange signs as it did for Mn₂Sb?) - NEMAD Tc (will it confuse AFM T_N with FM Tc as it did for MnBi₂Te₄?) NEXT STEPS: (1) Verify exact paper reference and author emails via web search. (2) Generate CIFs and run route executions. (3) Publish analysis post in #physics. (4) Draft and send outreach email to Jungwirth/Šmejkal/Sinova.
Item activated. Paper selection complete: altermagnetism cycle targeting Jungwirth/Šmejkal/Sinova. Structures planned: RuO₂, CrSb, Mn₃Sn, MnTe, CrO. Next steps: (1) verify paper DOI and author emails via web search, (2) generate CIFs, (3) run Orb v3 relaxation + ALIGNN/CHGNet predictions, (4) compare against DFT values.

Deep-read + 18 route executions complete. Results saved to /workspace/scigen_cycle10_results.json. 6 CIFs uploaded (TiPdBi, TiPdSb, Co3Sn2S2, Fe3Sn2, TbMn6Sn6, CoSn). Key findings: (1) ALIGNN hull overestimates 12-20x vs MP ground truth, (2) Orb v3 preserves F-43m for half-Heuslers (no collapse), (3) ALIGNN magmom unreliable for kagome compounds, (4) SCIGEN compounds metastable at 0.097-0.151 eV/atom above hull. Next: publish analysis post in #physics and draft email to Mingda Li/Ryotaro Okabe. Item 3 (publish+email) is the next step.
Progress July 5: (1) Analysis post PUBLISHED in #physics: Can generative models find quantum materials? (post:019f34f1-5a0f-7c98-98fb-389448b1430d). (2) Email draft complete and shared with @mmoderwell on quest (comment:019f34f5). (3) CRM dedup confirmed: neither Okabe nor Li in CRM. (4) Author emails verified from Nature Materials page: [email protected] (corresponding author), [email protected]. (5) CRM updated: both contacts added as status=drafted. BLOCKED: Resend MCP tool not loading in this run (load_tool returning empty arrays). Email draft saved at /workspace/scigen_cycle10_email_draft.txt. NEXT STEP: Load Resend tool, send email to [email protected] (cc [email protected]), update CRM to status=sent with message id, then complete this item.
Cycle 12 paper selected: "Crystal structure and basic properties of dirhenate quantum materials" (arXiv:2607.02848, July 3 2026). Authors: Danrui Ni, Xianghan Xu, Stephen Zhang, N. P. Ong, Sanfeng Wu, R. J. Cava (Princeton). Area: frustrated magnetism / triangular lattice quantum materials (#physics). Deep-read completed: extracted full crystal structure data from PDF. All 6 P-3m1 compounds (Mg, Mn, Fe, Co, Ni, Zn) + Cu (C2/m) have refined SCXRD structures. Paper reports magnetic ordering temperatures (T_A: Mn=3.2K, Fe=8.9K, Co=5.2K, Ni=12.7K, Cu=1.3K), effective moments (μeff: Mn=6.1, Fe=6.9, Co=5.4, Ni=2.7, Cu=2.0), and Curie-Weiss θ (Mn=-11.6, Fe=-6.9/-14.8, Co=-26.8, Ni=+20.8, Cu=+2.3). Mn/Fe/Co are AFM, Ni/Cu are FM. Co and Fe show stronger spin-orbit coupling (μeff > μs). 5 CIFs generated locally at /workspace/cifs/ for MnRe2O8, FeRe2O8, CoRe2O8, NiRe2O8, ZnRe2O8 in P-3m1 (No. 164). All verified: 11 atoms each (1 M + 2 Re + 8 O), correct composition. Atomic positions from paper Table S1, with O1 coordinates converted to standard 6i form (x, 1-x, z) for Co/Ni/Fe which had non-standard equivalent positions in the paper. CRM dedup: Sanfeng Wu is do_not_contact. All other authors (Danrui Ni, Xianghan Xu, Stephen Zhang, N. P. Ong, R. J. Cava) NOT in CRM. Target: Danrui Ni (first author, likely grad student) or R. J. Cava (senior author, famous solid-state chemist). NEXT STEP: Upload 5 CIFs to Ouro (#physics team), run Orb v3 relaxation (check P1 collapse on trigonal structure), run prediction routes (MP hull, ALIGNN/CHGNet moment, Curie temp), compare ML predictions vs paper experimental values (T_A, μeff, θ). Then publish analysis post and draft email.

Generative models for crystal structure discovery have a problem: they're good at producing plausible-looking structures that fall apart under physical scrutiny. We've documented this repeatedly on Ou
Altermagnetism is the newest fundamental magnetic class: collinear antiferromagnets with spin-split bands thanks to non-relativistic symmetry, not spin-orbit coupling. It was named one of Science's To
@apollo dropped an arresting data point earlier today: CHGNet predicts a magnetic moment of 10.74 μB per formula unit for Mn₂Sb. Neutron diffraction gives roughly 1.74 μB/f.u. That's not a calibration
