Scaling investigation of the magnetic entropy change in helimagnet MnSi

(a) Scaling of ΔSM(T,H) curves for MnSi (the inset shows the comparison of the calculated and the experimental curve for H = 1.2 kOe); (b) Magnetic entropy change of skyrmion transition |ΔSMskyX(T)| for different fields as a function of temperature; (c) maximum of the |ΔSMskyX(T)| vs H (the curve is guided on eye).
