Extended Data Fig. 5: Current-induced magnetisation switching efficacy.

a The second harmonic voltage \({V}_{x}^{2\omega }\) measured as a function of magnetic field at 150 K, for the left-handed (LH) helix with pitch length L = 0.5 μm, with an AC current of 40 μA. b The response of the device in the current-induced switching experiment, showing the measured change in the second harmonic longitudinal voltage \(\Delta {V}_{x}^{2\omega }\) at 150 K and zero applied magnetic field, plotted as a function of t, and measured with an AC current of 40 μA. In both plots, the horizontal coloured lines are a guide to the eye. Comparison of the change in \({V}_{x}^{2\omega }\) indicates that close to 100% of the magnetisation is reversed within the helical device.
