Lab-deposit template for the Mn-Ge-N nitrogen-vacancy series (Mn12Ge4N3 to Mn3GeN). One row per specimen, capturing successful samples and null results equally. Required fields: nominal + assayed composition, phase fractions, lattice parameters, nitridation conditions, raw-data file reference (Ouro file asset UUID or repository URL), instrument + calibration metadata, magnetic-order assignment, moment normalization basis, and an explicit failure reason when the result is a null or failed sample. The two EXAMPLE rows are illustrative placeholders, not measurements. Accompanies the Mn-Ge-N vacancy-series experiment matrix (asset 01a02a6c-95c1-7396-88f0-692351c3c5f6) and the measured magnetic data call (asset 019fe745-c604-7a79-b2be-497c19118cb4).
