On the Perovskites Ba₂LnSbO₆ (Ln = Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb)

Abstract

Polycrystalline Ba2LnSbO6 (Ln = Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb) are cubic, perovskite‐type compounds, space group Fm3m (No. 225), Z = 4, with a values from a = 8.544(2) Å for Ba2NdSbO6 to a = 8.368(1) Å for Ba2YbSbO6. X‐ray diffraction data for all the compounds and the results of magnetic measurements for two of them are given.

On Characterization of Barium Rare-Earth Antimonates: Ordered Perovskites Suitable as Substrates for Superconducting Films

“…It is somewhat unusual to find a rare-earth cation occupying the B positions of a perovskite: given their relatively (2) high size they are more often found in the A sublattice, e.g., in the well known RFeO family. A bond valence analysis, after Brown's model (16,17), can help give an idea of how comfortable a rare-earth cation is in the B sublattice of a perovskite.…”

Synthesis, characterization, sintering and dielectric properties of nanostructured perovskite-type oxide, Ba2GdSbO6

“…Ba 2 LnSbO 6 (Ln = lanthanides) compounds with double perovskite A 2 BB′O 6 structure have been extensively studied in the past (Blasse 1965;Garcia Cascado et al 1984;Alonso et al 1997;Karunadasa et al 2003). Among these materials, Ba 2 GdSbO 6 compound was of special interest because of its applications (Kurian et al 1995) as substrate for high temperature superconducting YBa 2 Cu 3 O 7-δ films.…”

Structural and magnetic characterization of manganite‐like Sr 2 FeMnO 6 as substrate for YBa 2 Cu 3 O 7–δ films

“…Thus, the whole XRD pattern of SFMO can be indexed in a A 2 BB'O 6 cubic cell with the cell edge a=2a p , where a p represents the cell lattice of the cubic perovskite. The XRD spectrum of SFMO is isostructural to Sr 2 NdSbO 6 -type complex cubic perovskite oxide reported in the Joint Committee on Powder Diffraction Standards (JCPDS) files [7], with the number 38-0817, as judged by the similarity in d spacing and intensity ratios. The presence of the superstructure reflection lines (111) and (311) in the XRD spectrum of SFMO is the signature of an ordered complex cubic perovskite structure.…”
