• m0 = Up-Up scattering, m1 = Down-Down scattering, m2 = Up-Down scattering, and m3 = Down-Up scattering, where Up and Down refer to the neutron's spin relative to the net magnetization before and after interacting with the sample.
• This model is meant for hexagonally-packed, magnetic, core-shell nanoparticles where their preferred magnetization direction is determined as a function of local packing anisotropy (dipolar interactions) and Zeeman energy.
