DELGADO, G. E. et al. Crystal structure and powder X-ray diffraction data of the super-paramagnetic compound CuFeInTe₃. Rev. mex. fis. [online]. 2021, vol.67, n.2, pp.305-311.  Epub 16-Feb-2022. ISSN 0035-001X.  https://doi.org/10.31349/revmexfis.67.305.

The crystal structure of the new CuFeInTe3 quaternary compound was studied by the Rietveld method from powder X-ray diffraction data. The CuFeInTe3 compound crystallize in the tetragonal CuFeInTe3-type structure with space group $\mathrm{P}\overline{4}2\mathrm{c}$ (N◦112), and unit cell parameters a = 6.1842(1) Å, c = 12.4163(2) Å, V = 474.85(1) Å3. The density of CuFeInTe3 is ρx = 5.753 g cm−3. The reliability factors of the Rietveld refinement results are R p = 5.5%, R wp = 6.1%, R exp = 4.7%, and S = 1.3. The powder XRD data of CuFeInTe3 are presented and the figures of merit of indexation are M 20 = 79.4 and F 30 = 43.3 (0.0045, 154).
