Research Abstract

The perovskite-type compounds containing both rare earth and osmium Ba2LnOsO6 (Ln = Pr, Nd, Sm-Lu) have been prepared. Powder X-ray diffraction measurements and Rietveld analysis show that Ln3+ 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 Ba2LnOsO6 (Ln = Pr, Nd, Sm, Eu, Lu) at 52-94 K. For Ba2TbOsO6 and Ba2YbOsO6, magnetic transitions due to the antiferromagnetic transition of the Tb3+ and Yb3+ are observed at 2.6 and 2.4 K, respectively. Neutron diffraction measurements for Ba2NdOsO6 show that the magnetic structure is of type I and the magnetic moments of Nd3+ and Os5+ ions are in the same direction in the ab-plane. Eu Mossbauer spectrum measurements show that the magnetic hyperfine field is 20 T.
