摘要:
Praseodymium-containing double perovskites (Ba1-xSrx)(2)PrRuO6 were prepared. They crystallize in a monoclinic structure with space group P2(1)/n in the range of 0 <= x <= 0.30. Magnetic susceptibility measurements show that all these (Ba1-xSrx)(2)PrRuO6 compounds order an antiferromagnetic transition at 95 <= T <= 117 K, and the Neel temperatures decrease with increasing Sr concentration (x value). Specific heat measurements and the magnetic entropy change for (Ba1-xSrx)(2)PrRuO6 also reveal the simultaneous magnetic ordering of Pr and Ru ions.
