      Multiple magnetic scattering has been considered before in the calculations of polarized neutron beam transmission through ferromagnets (Halpern & Holstein, ; Hiismaki, ) and in the interpretation of critical scattering in ferromagnets (Toperverg et al., ) Pulsed neutron sources enable the simultaneous measurement of small-angle neutron scattering (SANS) and Bragg edge transmission. This simultaneous measurement is useful for microstructural characterization in steel. Since most steels are ferromagnetic, magnetic scattering contributions should be considered in both SANS and Bragg edge transmission
