Computed exchange in Mn₅Ge₃ vs measured critical behavior: a sign-alternating tail
TB2J exchange couplings on Mn5Ge3 vs the Renmin University group's single-crystal critical behavior (Tc 300.29 K, beta 0.336, J(r)~r^-4.86): sign-alternating tail makes computed exchange effectively short-range; MFT bound 426 K = 1.42x measured.
Mn₅Ge₃ as a validation anchor: route predictions vs. experiment in the Mn-Ge magnetic family
CHGNet+CatBoost route predictions on Mn5Ge3 (Tc=431K vs experimental 294K, Ms=763 kA/m, FM confirmed) as a validation case, connecting Jin Tang's Mn5Ge3.2 high-pressure work to the Mn3GeN blind-spot quest.
