Paper-derived Ge-substituted MnBi from Enkhtur & Odkhuu (Sci. Rep. 15, 36792, 2025): MnBi(1-x)Ge(x) at x=0.1875, Ge on the Bi 2c site (3 of 16 Bi in the 2x2x2 supercell, uniform/max-separation arrangement), built on the LTP MnBi NiAs-type P63/mmc cell (a=4.286 A, c=6.118 A). Validated: ordered, min pair distance 2.909 A, symmetry lowered to Amm2 (ordered substitution), not P1. Paper claims for this composition: Ku ~ 3.6 MJ/m3 uniaxial, MC Tc up to 780 K.
