Abstract
The aim of this chapter is to point out the relevance of magnetization density studies by means of polarized neutron diffraction (PND) for understanding the magnetic behaviour of materials. Recent advances in the PND technique are overviewed. Major improvements in PND data analysis concern magnetization density reconstruction using the Maximum of Entropy Method (MEM) and the new method based on the local susceptibility tensor approach for non collinear moments in strongly anisotropic materials. The well established model refinement methods are based on the atomic orbital (AO) model and the multipole model. The interest of magnetization density studies for studying novel molecule-based magnetic materials is demonstrated on the basis of selected examples.
