A profile refinement method for nuclear and magnetic structures
TL;DR: In this paper, a structure refinement method was described which does not use integrated neutron powder intensities, single or overlapping, but employs directly the profile intensities obtained from step-scanning measurements of the powder diagram.

Recent advances in magnetic structure determination by neutron powder diffraction
TL;DR: In this article, the main formulas governing the analysis of the Bragg magnetic scattering are summarized and shortly discussed and the method of profile fitting without a structural model to get precise integrated intensities and refine the propagation vector(s) of the magnetic structure is discussed.

Representation analysis of magnetic structures
TL;DR: In this paper, the authors show that the only invariant magnetic structures describable by magnetic groups belong to real one-dimensional representations of the 230 conventional space groups and allow one to assign irreducible representation of the actual space group to all known magnetic structures.
