[1] | Pankratov D. A., Yur’ev A. I. Mössbauer diagnostics of the isomorphic substitution of iron for aluminum in triclinic iron vanadate // Bulletin of the Russian Academy of Sciences: Physics. — 2013. — Vol. 77, no. 6. — P. 759–764. Mössbauer spectroscopy and X-ray powder diffractometry (XRD) phase analysis are used to study mixed vanadates with the composition AlxFe(3–x)V3O12, where x is 0, 0.3, 1.0, 1.5, 2.0, 2.7, and 3.0. Mössbauer spectroscopy is used to study the distribution of trivalent cations over different crystallographic positions. It is shown that the distribution of aluminum atoms differs from those expected from statistic and thermodynamic models. [ DOI ] |
