Figure 2
(a) 2π-azimuthally-averaged total nuclear and magnetic SANS cross-section dΣ/dΩ of nanocrystalline Co versus momentum transfer q at a series of internal magnetic fields (see inset) (log–log scale) (k0 ∥ H0). (b) Corresponding spin-misalignment SANS cross-section dΣSM/dΩ obtained by subtracting the dΣ/dΩ data at 14.71 T [orange data points in (a)] from the dΣ/dΩ at lower fields. (c) Magnetization curve of nanocrystalline Co (only the upper-right quadrant is shown). The large red data points indicate the internal-field values where the SANS data were taken. The horizontal dashed line indicates the saturation-magnetization value of μ0Ms = 1.80 T. The vertical dashed line indicates the approach-to-saturation regime (M/Ms ≳ 96%).
