摘要：

The perovskite-type compounds containing both rare earth and osmium Ba(2)LnOsO(6) (Ln=Pr, Nd, Sm-Lu) have been prepared. Powder X-ray diffraction measurements and Rietveld analysis show that Ln(3+) and Os5+ ions are structurally ordered at the M site of the perovskite BaMO3. Magnetic susceptibility and specific heat measurements show that an antiferromagnetic ordering of Os5+ ions has been observed for Ba(2)LnOsO(6) (Ln=Pr, Nd, Sm, Eu, Gd, Lu) at 65-71 K. Magnetic ordering of Ln(3+) moments occurs when the temperature is furthermore decreased. (C) 2013 Elsevier Inc. All rights reserved.
