SANS with longitudinal polarization analysis is a powerful technique to study magnetic morphology and domain interactions with directional sensitivity on the nancoscale. Here, by explicitly isolating the various nuclear-magnetic and magnetic-magnetic interference scattering contributions, we extend the separation of nuclear and magnetic scattering from the simplified coordinate-axis approach into the full spatial regime probed by SANS under a variety of conditions. The result is an enhanced ability to analyze magnetically and structurally anisotropic samples, which is especially important for magneto-responsive materials including magnetic fluids. We also discuss the relationship between observable interference patterns and the underlying magnetic symmetry.
