Fig. 4

Field-dependent scattered intensity maps for a the angle ϕ and b the magnitude ∣q∣ of the scattering vector, as defined in c. The measurements shown in a and b were carried out at 45 K using the field-cooling protocol. The temperature dependence of the ϕ-field plots is shown for 30, 35, 40, 45, and 50 K, in d–h, respectively. The red and green color scale data in b correspond to the intensity from the helical/conical and skyrmion modulation, respectively. These intensity plots are obtained by integrating within the regions of interest for the conical/helical and first-order skyrmion peaks as shown in Fig. 2d.
