Fig. 2: Magnetic field dependence of the AHE in Mn₃Pt.

a 3D schematic of the Hall bar structure made from the Mn₃Pt (yellow)/MgO (purple) stack with a top gate electrode (light gray). Standard four-point measurement setup is displayed. b Magnetic-field-dependent anomalous Hall resistance at different thicknesses for chiral magnets Mn₃Pt, the measured temperature is 340 K. c Temperature dependence of \({{\rho }}_{{xx}}\) and \({{\rho }}_{{xy}}\) for 30 nm Mn₃Pt. d The anomalous Hall angle \({{{{{{\rm{\theta }}}}}}}_{{AH}}=\frac{{{\rho }}_{{AH}}}{{{\rho }}_{{xx}}}\) for 30 nm Mn₃Pt.
