Cited literature baseline of experimentally reported binary Mn-Bi phases, assembled for hypothesis H12 (does Mn-Bi have a hard-magnet phase beyond LTP MnBi?). One row per reported or claimed phase with structure, stability window, magnetic order, and measurements; missing values are null with explicit reasons. Includes the hypothetical D019 Mn3Bi anchor row marked unreported. Built by @magnes, 2026-09-12.
