Rietveld refinement for Sr(Ba)-bearing ye'elimite
Advances in Cement Research, 2016Ye'elimite-containing cements are of growing research interest owing to their characteristic properties. Strontium (barium) (Sr(Ba))-bearing ye'elimite is synthesised by the substitution of Sr2+(Ba2+) ions for Ca2+ ions in ye'elimite. Here, Rietveld refinement for Sr(Ba)-ye'elimite is reported.

Rietveld Refinement of New Ternary Compound Al14Dy5Si
Journal of Rare Earths, 2006Abstract A new ternary compound Al14Dy5Si was discovered and studied by means of X-ray powder diffraction technique. The ternary compound Al14Dy5Si has a hexagonal BaPb3-type structure, space group R 3 m (No. 166), the lattice parameters a = 0.61482(1) nm, c = 2.09780(2) nm.

Rietveld refinement of energy-dispersive synchrotron measurements
Zeitschrift für Kristallographie, 2011Abstract In the past two decades the energy-dispersive diffraction (EDD) method has become a powerful tool in many fields of materials research such as residual stress, texture, and crystal structure analysis, because of its favorable ratio of a comparatively low experimental effort in form of a simple and fixed instrumental setup to a ...

Quantitative texture analysis by Rietveld refinement
Journal of Applied Crystallography, 1997A generalized spherical-harmonic description of the texture for polycrystalline materials has been implemented in a multiple-phase/multiple-data-set Rietveld refinement code. It has been tested using two sets of neutron time-of-flight data taken from a standard calcite sample previously used for a round-robin study [Wenk (1991). J. Appl. Cryst.

Restraints and constraints in Rietveld refinement
1993Abstract In the same year as Rietveld’s paper, ‘A Profile Refinement Method for Nuclear and Magnetic Structures’ appeared (Rietveld 1969), Meier and Villiger ( 1969) published an article, the German title of which could be translated as ‘A Distance Refinement Method for the Determination of Atomic Coordinates of Idealized Framework ...

Key insights in disseminating Multidimensional Rietveld Refinement
Our group specializes in the development of neutron powder diffraction methods, primarily utilizing the neutron time-of-flight diffractometer POWTEX, which was developed in collaboration with Forschungszentrum Jülich at FRM-II in Garching. As part of the DAPHNE project, we are expanding these methodologies to enhance their applications, with a strong ...Meinerzhagen, Yannick +2 more

Combined X-ray and neutron Rietveld refinement
1993Abstract As is noted in Chapter 1, a neutron or X-ray powder diffraction pattern can be modelled from descriptions of the crystal structure of the sample, both instrumental and sample contributions to peak broadening, intensity effects such as absorption and extinction, and a background contribution.
