a-c First harmonic resistance \({R}_{{xx}}^{1\omega }\) measured as a function of magnetic field B at 10 K with an AC current of 10 μA, for the helical devices with pitch length L = 0.5, 1.0 and 2.0 μm. d-f The antisymmetrised second harmonic voltage \({V}_{x}^{2\omega }\) measured at 10 K with various AC currents, demonstrating the expected I2 scaling for all three devices.
