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.

MAGNDATA ID Collinearity i Whether the magnetic configuration was collinear in MAGNDATA or constructed from a noncollinear entry. Phase i Some materials also have non-altermagnetic (AM) phases predicted; AM for altermagnet and FiM for ferrimagnet. Wave i Symmetry wave-class shorthand derived from the parent and halving-subgroup Laue classes used in the altermagnetism analysis. SYMPREC i Spglib symmetry tolerance symprec, shown as an exponential base-10 value. BNS (MCIF) i BNS setting indicated in the source MCIF file. G H
