Structural and magnetic properties of the (Bi2-xPrx)Ru2O7 pyrochlore solid solution (0 <= x <= 2)
Siwar Zouari, Rafik Ballou, Abdelwaheb Cheikh-Rouhou +1
We report a detailed study of structural and magnetic properties of the pyrochlore-type (Bi2-xPrx)Ru2O7 series. Eleven compositions with 0 <= x <= 2 were prepared by solid state re…
Synthesis and structure of new pyrochlore-type oxides Ln2ScNbO7 (Ln = Pr, Nd, Eu, Gd, Dy)
Siwar Zouari, Rafik Ballou, Abdelwaheb Cheikh-Rouhou +1
We report the synthesis and structural study of mixed oxides in the Ln2ScNbO7 series. New phases with Ln = Pr, Eu, Gd and Dy are obtained. All crystallize in the cubic pyrochlore s…
Effect of mixed alkali-element substitution on structural and magnetic properties of praseodymium manganites Pr0.9(Na1-xKx)0.1MnO3
Siwar Zouari, Laurent Ranno, Abdelwaheb Cheikh-Rouhou +1
The effect of cationic size mismatch at the A site at constant manganese valence on the structural and magnetic properties of a perovskite-type rare-earth manganate was investigate…
Structural and magnetic properties in the ruthenate Bi2.67Pr0.33Ru3O11
Siwar Zouari, Abdelwaheb Cheikh-Rouhou, Rafik Ballou +1
An unreported praseodymium substituted phase of the Bi-Ru-O system with formula Bi2.67Pr0.33Ru3O11was prepared. Its crystal structure and magnetic properties were investigated. Pr…
