Fig. 5: Numerical calculations of total scattering intensities and second moments.

The numerically calculated a, b integrated intensity and c, d 2nd moments of the sum signal (ferromagnetic order) and the difference signal (chiral magnetic order) as a function of the a, c domain-wall width and b, d the transversal magnetization fluctuation strength (cone angle in degrees). The 100% value in a, c corresponds to the room temperature domain-wall width of 8 nm. The dashed lines in b, d correspond to the case of fluctuation in the whole system, while the solid lines correspond to the case of reduced fluctuations within the domain walls.
