a Schematic of the L21-ordered structure of Co2MnGa. Dependence on perpendicular external magnetic field (Hz) of b \({\rho }_{yx}^{{\rm{A}}}\) and c \({E}_{xy}^{{\rm{A}}}\) normalized by given temperature gradient Tx in the Co2MnGa films. d \({E}_{xy}^{{\rm{A}}}\) measured by giving the perpendicular temperature gradient Tz and sweeping the in-plane magnetic field Hx for the sample with Nv = 28.5. Dependence on total valence electron number Nv of e ρxx, f \({\rho }_{yx}^{{\rm{A}}}\), g \({\sigma }_{xy}^{{\rm{A}}}\), h Sxx, i \({S}_{xy}^{{\rm{A}}}\), SI and SII and j \({\alpha }_{xy}^{{\rm{A}}}\). Green dashed lines in ej indicate Nv for the stoichiometric composition. All error bars represent standard deviation. k Relationship between \({\alpha }_{xy}^{{\rm{A}}}\) vs. \({\sigma }_{xy}^{{\rm{A}}}\) in our Co2MnGa films (red circles) and different magnets (gray squares: taken from ref. 34).
