摘要：

Na2Mn2(1 - x)Cd2xFe(PO4)(3) (0 <= x <= 1) phosphates were prepared by solid state reaction and characterized by powder X-ray diffraction, magnetic susceptibility and Mossbauer spectroscopy. The X-ray diffraction patterns indicated the formation of a continuous solid solution which crystallizes in the alluaudite structural type characterized by the general formula X(2)X(1)M(1)M(2)(2)(PO4)(3). The cation distribution, deduced from a structure refinement of the x = 0, 0.5 and 1 compositions, is ordered in the X(2) sites and disordered in the remaining X(1), M(1) and M(2) sites. The magnetic susceptibility study revealed an antiferromagnetic behaviour of the studied compounds. The Fe-57 Mossbauer spectroscopy confirmed the structural results and proved the exclusive presence of Fe3+ ions. (C) 2011 Academie des sciences. Published by Elsevier Masson SAS.
