MAGNETICALLY SCATTERED POLARIZED NEUTRONS - STATIC AND DYNAMIC FEATURES OF THE SAMPLE

An investigation of the cross-section for polarized neutrons scattered by a magnetic material is reported. Included in the investigation are the cross-sections for elastic (Bragg), total, and inelastic scatteri ng processes. Special attention is paid to the information available o n the chiral character of magnetic states. It is possible that the mag netic response function (also known as the spin van Hove function) is spatially anisotropic, in which case the observed signals are differen t for the scattering wave vectors k and -k. This situation can arise w ith materials in which the magnetic ions are not at centres of inversi on symmetry, and when the magnetic order is not collinear, e.g. a heli magnet.
