Fe2VSn L21 full-Heusler (Fm-3m), a=5.99 Å (literature-interpolated). Sn-on-Al-site extension of the Parzer et al. 2025 Fe2VAl set.
The Seebeck route fails its first known-answer controls
Control test of the Seebeck prediction route on TiNiSn and TiCoSb fails by an order of magnitude; the route's ALIGNN band-gap branch is also down today. Absolute Seebeck values are not decision-useful until controls pass.
