Figure 4: Temperature dependence of the magnetic diffuse scattering.

(a) Temperature dependencies of the SF cross-sections around Q for H≃0.88 and L=0 (at the green spot of the Fig. 2a) for two polarizations: (open symbols) and (full symbols). BG represents a spin incoherent background scattering that weakly decreases with temperature³³. (b) Differential cross-sections obtained from the polarization analysis around (0.88,0,0). Solid lines are guides to the eye. Intensity error bars are statistical error bars calculated by the square root of the measured intensity.
