: Specialized tools for determining complex magnetic configurations from neutron diffraction data. fullprof

Widely considered the most used package for determining magnetic structures, utilizing magnetic space groups (MSG) and representation analysis. Rietveld constant wavelength 1

FullProf is a specialized software suite designed for the crystallographic analysis of neutron and X-ray diffraction data. Primarily used for Rietveld refinement, it allows researchers to determine and refine the structural properties of crystalline materials, including crystal and magnetic structures, from powder or single-crystal data. Developed by Juan Rodríguez-Carvajal at the Institut Laue-Langevin (ILL) , it has become a fundamental tool in materials science for studying composition, purity, and microstructural details like grain size and strain.
