a Schematic diagram showing a possible current flow pattern, which generates a directional flow (DC component) from an oscillating input (AC). b The DC electric field \({E}_{xy}^{DC}\) and harmonic electric fields \({E}_{xy}^{n\omega }\) (n = 1, 2 and 3) as a function of current density J1ω at T = 1.7 K and B = 9 T for the longitudinal configuration with parallel magnetic field B and electric field E (B // E). While \({E}_{xy}^{DC}\) and \({E}_{xy}^{2\omega }\) are finite, \({E}_{xy}^{\omega }\) and \({E}_{xy}^{3\omega }\) are zero. c A phase diagram constructed in the current density J1ω-magnetic field B plane using \({E}_{xx}^{DC}\), \({E}_{xy}^{DC}\) and \({E}_{xy}^{2\omega }\) measurements at different magnetic field. d, e The enlarged \({E}_{xy}^{DC}\) and \({E}_{xy}^{2\omega }\) as a function of J at small J in different magnetic fields at T = 1.7 K, respectively.
