... different aspects of neutron scattering from magnetic mate- rials. I intentionally chose the title Neutron Scattering from Magnetic Materials rather than Magnetic Neutron Scattering to emphasize ... mainly consider magnetic neutron scattering. However, neutron scattering intensity from magnetic materials is a superposition of both types of scattering. In or...
