Fig. S1. (a), (b) Arrott plots of Mn4.9Zn0.1Ge3 and Mn4.8Zn0.2Ge3, respectively, and (c) and (d) magneto-entropy transformation plots. Figures S2. (a) and (b), (c) and (d), (e) and (f) show the normalization curves, TEC, and image relationships of Mn4.9Zn0.1Ge3 and Mn4.8Zn0.2Ge3 normalized curves, TEC, and the image relations of TEC, || and RC, RCP in 0-7T. Figure S3. shows the KF fitting curves for Mn4.9Zn0.1Ge3 and Mn4.8Zn0.2Ge3.Figures S4. Plots demonstrating the temperature scaling of M=M〖|ε|〗^(-β)and H〖|ε|〗^(-(β+γ)) at T > TC and T < TC, correspondingly.Figures S5. Law of variation of spontaneous magnetization MS and initial magnetization χ_0^(-1) with temperature for Mn5-xZnxGe3 compounds.
