Automatic Rietveld refinement by robotic process automation with RIETAN-FP
Science and Technology of Advanced Materials: Methods, 2022 Rietveld analysis necessitates the manual trial-and-error refinement of various parameters. To reduce human costs and resources, we have developed a robotic process automation (RPA) system for the Rietveld analysis program RIETAN-FP.

A simple solution to the Rietveld refinement recipe problem. [PDF]
J Appl CrystallogrRietveld refinements are widely used for many purposes in the physical sciences. Conducting a Rietveld refinement typically requires expert input because correct results may require that parameters be added to the fit in the proper order. This order will depend on the nature of the data and the initial parameter values. A mechanism

Rietveld refinement guidelines [PDF]
Journal of Applied Crystallography, 1999 A set of general guidelines for structure refinement using the Rietveld (whole-profile) method has been formulated by the International Union of Crystallography Commission on Powder Diffraction. The practical rather than the theoretical aspects of each step in a typical Rietveld refinement are discussed with a view to guiding newcomers in the field ...

Recommended X-ray single-crystal structure refinement and Rietveld refinement procedure for tremolite [PDF]
Acta Crystallogr B Struct Sci Cryst Eng Mater, 2021 A detailed description of the structure of the amphibole-supergroup minerals is very challenging owing to their complex chemical composition that renders the process of cation partition extremely difficult, particularly because of the occurrence of ...
