Clifford Shull and J. Samuel Smart used neutron diffraction to detect antiferromagnetism. Oppositely oriented magnetic sublattices can have no net bulk magnetization, yet their spatial order produces a distinct scattering pattern because neutrons interact with magnetic moments. The experiment therefore probes internal magnetic arrangement, not just the total magnetic moment of a sample. It established neutron scattering as a way to reveal ordered magnetism that bulk magnetic measurements can conceal.[ref]
