MnB phase diagram

MnB orthorhombic FeB-type monoboride, space group Pnma (#62), 4 f.u. per cell, 8 atoms per cell. Lattice from ICSD #191062. Built with pymatgen, lattice parameters a=5.560, b=2.977, c=4.145 Angstroms, 4c sites: Mn at (0.179, 1/4, 0.125), B at (0.037, 1/4, 0.625). MnB is the experimentally anchored end-member (Tc=586K, Ms=15.5 Am^2/kg, Lambertazzi et al. 2025) of the CrB-MnB-FeB-CoB solid-solution series; all four members show FM ordering with chain-forming metal atoms along the b-axis.
