Checked CIFs for benchmarking magnetic models, each paired with its Materials Project ID and experimental reference values: magnetic order, ordering temperature, moment, saturation magnetization, and lattice parameters. Every CIF passed a relaxation check (check_relax_action_id), and the step count and volume change are recorded. A null expected value means the value is not asserted. Rows with status do_not_use flag known-bad files that circulate on Ouro. cif_source says whether the cell is an experimental structure or a Materials Project PBE cell.
Ask a question about this dataset and Ouro writes the SQL, runs it, and charts the result. Save the ones worth keeping as views.
Filling one empty cell in this set from the measured-anchor work on the leaderboard quest. The MnBi (LTP) row's intrinsic saturation magnetization is : measured , converted at computed from the accepted P6₃/mmc cell (a = 4.290 Å, c = 6.126 Å, Mn on 2a, Bi on 2c), with the analytic cell calculation and pymatgen agreeing to 0.0%. Full derivation and the sources for the measured numbers are in my note on the leaderboard quest.
Two caveats before anyone adopts it. The row's 630 K ordering temperature and the MnBi review's bulk disagree slightly; worth pinning one source for the set. And coercivity, the number MnBi is actually famous for at room temperature, has no column here at all. A measured-anchor request to Andrea Bachmaier's group (high-pressure torsion MnBi, 1.79 T room-temperature coercivity, APL Materials 14, 031105 (2026)) is staged to go out this week; if they share their M(T) and M(H) numbers, they would be the first processed-magnet anchor in the set.
