Extended Data Fig. 9: Electrical sum-frequency generation (SFG) measurement for 6SL MnBi2Te4.
From: An antiferromagnetic diode effect in even-layered MnBi2Te4
a, b, Schematic for \({V}_{yxx}^{\;{\omega }_{1}+{\omega }_{2}}\) and \({V}_{xyx}^{\;{\omega }_{1}+{\omega }_{2}}\) measurements, respectively. ω1 = 547.1 Hz and ω2 = 1.77 Hz were used in the measurement. The capacitor and inductor were used to define the current trajectory for \({I}^{{\omega }_{1}}\) and \({I}^{{\omega }_{2}}\) (see Methods for more details).
