About the topic
Scattering of radiation is a very important experimental tool in the physical sciences, and neutron scattering excels in the investigation of magnetic materials. Indeed, most magnetic structures − motifs of dipole moments − are derived from neutron Bragg diffraction patterns. Julian Schwinger launched studies in 1937 by proving that neutrons are deflected by magnetic dipole moments. Eight decades later, Dirac multipoles have been shown to deflect neutrons, and the conjecture has been confirmed by neutron Bragg diffraction from a ceramic (high Tc) superconductor.
