Sw. Lovesey et Gi. Watson, MAGNETICALLY SCATTERED POLARIZED NEUTRONS - STATIC AND DYNAMIC FEATURES OF THE SAMPLE, Journal of physics. Condensed matter, 10(30), 1998, pp. 6761-6769
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.
