Spin-splitting metrics

Max SS i Largest spin splitting identified within ±3 eV of the Fermi level in the high-throughput DFT workflow.

0.457 eV

Avg SS i Brillouin-zone average of the largest spin splitting at each sampled k-point in the same energy window.

FΔ i Fraction of near-Fermi bands and sampled k-space showing appreciable spin splitting after the numerical noise cutoff.

35.0%

Symmetry screening

The summary table shows one row per linked MAGNDATA record and symmetry-precision variant. If a MAGNDATA ID has multiple Spglib symprec values in the source data, it appears on multiple rows. The cards below keep the same expanded per-variant detail view, including wave classification and mismatch metrics.
