Results for the magnetization and the SANS observables of a dilute ensemble of uniaxial Stoner–Wohlfarth particles with ku1 = +1 and ku2 = 0 [case (i)] (B ⊥ k0). The (spherical) particle diameter is D = 10 nm. (a) Two-dimensional magnetic SANS cross sections dΣM, ⊥/dΩ at saturation (sat), remanence (rem) and at the coercive field (coe); (b) hysteresis loop [\overline{m}_{z}(B)] (the reduced remanence and the coercivity are indicated); (c) one-dimensional 2π azimuthally averaged magnetic SANS cross sections [I_{\perp}(q) = ({{{\rm d}\Sigma_{M,\perp}} / {{\rm d}\Omega}})(q)]; (d) pair-distance distribution functions p⊥(r); (e) correlation functions c⊥(r); and (f) anisotropy parameter A⊥(B).
