Fig. 3: Nernst effect of Co2MnGa.
a Magnetic field-dependence of the Nernst thermopower (Syx) of Co2MnGa at different temperatures T. The inset shows the extracted anomalous Nernst thermopower (\(S_{yx}^A\)) extrapolating the slope of the high-field (above 1 T) data points as a function of T. b Magnetic field-dependence of the transverse thermoelectric conductivity (αyx) at different T. c Theoretically calculated anomalous Nernst conductivity (\(\alpha _{yx}^A\)) as a function of the chemical potential with respect to the charge neutrality point E0 at T = 300 K for Co2MnGa. The dashed lines indicate different positions of the Fermi level EF. d T-dependence of the experimentally determined \(\alpha _{yx}^A\). The inset of the plot shows the theoretically estimated temperature dependence of \(\alpha _{yx}^A\) at the Fermi level positions marked in c
