| dc.description.abstractEn | Na<sub>2</sub>Mn<sub>2(1 − <i>x</i>)</sub>Cd<sub>2<i>x</i></sub>Fe(PO<sub>4</sub>)<sub>3</sub> (0 ≤ <i>x</i> ≤ 1) phosphates were prepared by solid state reaction and characterized by powder X-ray diffraction, magnetic susceptibility and Mössbauer 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 <i>X</i>(2)<i>X</i>(1)<i>M</i>(1)<i>M</i>(2)<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub>. The cation distribution, deduced from a structure refinement of the <i>x</i> = 0, 0.5 and 1 compositions, is ordered in the <i>X</i>(2) sites and disordered in the remaining <i>X</i>(1), <i>M</i>(1) and <i>M</i>(2) sites. The magnetic susceptibility study revealed an antiferromagnetic behaviour of the studied compounds. The <sup>57</sup>Fe Mössbauer spectroscopy confirmed the structural results and proved the exclusive presence of Fe<sup>3+</sup> ions. | |
