内容注記
  • Abstract en New fluorite-related quaternary rare earth oxides Pr2YRuO7 and La2TbRuO7 have been prepared. They crystallize in an orthorhombic superstructure of cubic fluorite with space group Cmcm. Through magnetic susceptibility and specific heat measurements, Pr2YRuO7 shows an anti ferromagnetic transition at 27 K, which is considerably lowered compared with that for Pr3RuO7. Analysis of the magnetic specific heat indicates that the magnetic behavior observed at 27 K for Pr2YRuO7 is predominantly due to the magnetic interactions between Ru ions, and that the interactions between the Pr3+ and Ru5+ ions are also important. La2TbRuO7 shows magnetic ordering at 9.0 K, which is ascribed to the magnetic ordering between Ru5+ ions from the analysis of the magnetic specific heat data.
