Polarized neutron diffraction
SPSMS, UMR-E CEA/UJF-Grenoble 1, INAC, 38054 Grenoble, France
This lecture addresses the different applications of polarized neutron diffraction, with or without subsequent polarization analysis, to the determination of magnetic structures, to the separation of magnetic and nuclear contributions and to magnetization distributions mapping. The first sections introduce some of the fundamental equations. Then the problems of magnetic domains, encountered in crystals and of particular importance as soon as polarized neutrons are concerned, are presented. The final sections discuss some of the different ways to use polarized neutron and are illustrated by examples.
