a-h, The antisymmetrized topological voltage response \({V}_{{yx}}^{{\rm{THE}}}\) of device 2, measured at 2.5 K and 1.3 T, plotted as a function of time t. Data were acquired with a sinusoidal current density (solid grey line), with peak amplitude \({J}_{{\rm{AC}}}^{\max }\) of 1.5 × 109 Am−2, and frequencies between 10 and 5,011 Hz. The horizontal dashed lines highlight the inflection points of the voltage response at low frequencies. At high frequencies, the nonlinearity of the voltage response is delayed due to the inertial-like motion of the skyrmion lattice in the creep regime.
