Thermoelectric vs magnetocaloric effects in MnSi

(A) Comparison between the measured magneto-Seebeck effect Δα_m = α_5T − α_0T (left axis) and the magnetocaloric effect ΔS_m for H = 5 T (right axis) for MnSi.²⁴ By considering 0.89 d-hole/MnSi obtained from Hall measurement,²⁵ the values of ΔS_m can be converted to those of Δα_MCE(T) in unit μV/K (see text), which agree reasonably with those of Δα_m.

(B) The measured values of α(T) for H = 0 T and 5 T,¹⁵ from which Δα_m is obtained.
