Extended Data Fig. 7: Amplitudes of Fourier components of the unit-cell-averaged DPC images.

Only the Fourier components corresponding to the double periodicity due to the magnetic structure are plotted. The amplitudes that are non-zero with statistical significance (the error bars are shown by ±2SE) are plotted in blue, whereas the remainder are plotted in red. The statistically significant non-zero amplitudes of Fourier components with the highest spatial frequency can be found at 6.83 nm⁻¹ = 1/(1.46 Å), indicated by the vertical arrow. Thus, the unit-cell-averaged magnetic field reconstruction contains statistically reliable spatial frequency information up to around (1.46 Å)⁻¹.
