P. Schleger et al., A GENERAL MAXIMUM-ENTROPY METHOD FOR MODEL-FREE RECONSTRUCTIONS OF MAGNETIZATION DENSITIES FROM POLARIZED NEUTRON-DIFFRACTION DATA, Acta crystallographica. Section A, Foundations of crystallography, 53, 1997, pp. 426-435
A general method for the model-free reconstruction of magnetization de
nsities is presented. The technique is based upon the maximum-entropy
principle and is valid for systems with any space-group symmetry, any
physically reasonable ordered moment and allows for the incorporation
of relevant corrections such as extinction. Thus, it is possible, for
the first time, to reconstruct the real-space magnetization densities
in essentially any physical system exhibiting a ferromagnetic spin ali
gnment (either natural or induced) from polarized neutron diffraction
experiments. The technique is illustrated for the purely organic ferro
magnet, l-2-p-(nitrophenyl)-3-oxido-4,5-dihydroimidazolium 1-oxyl.
