“…The buckling of the MO 6 results in M O M angles of approximately 145° along the chain axis. Members of the RE 3 MO 7 family include RESbO 7 [11], RENbO 7 [11,12], REMoO 7 [13], RERuO 7 [14][15][16], RETaO 7 [11], REReO 7 [17,18], REOsO 7 [19][20][21][22], and REIrO 7 [23,24], which collectively represents a considerable degree of chemical diversity. Possibly due to the zig-zag configuration of the octahedral chains, the electrons are localized on the M cation and therefore prime candidates for one-dimensional magnetic behavior.…”

“…These octahedra share corners forming one-dimensional chains which are oriented along the c-axis. The same space group Cmcm has been applied for Ln 3 RuO 7 (Ln = La ~ Gd) [2][3][4][5][6][7][8][9][10][11][12][13], 6 (ZFC) and field-cooled (FC) conditions. The former was measured upon heating the sample to 400 K under the applied magnetic field of 0.1 T after zero-field cooling to 1.8 K. The latter was measured upon cooling the sample from 400 to 1.8 K at 0.1 T.…”

Ternary rare-earth antimonates Ln 3 SbO 7 (Ln = rare earths) were prepared, and their structures were determined by X-ray diffraction measurements. They crystallize in an orthorhombic superstructure of cubic fluorite (space group Cmcm for Ln = La, Pr; Ccmm for Ln = Sm -Dy), in which Ln 3+ ions occupy two different crystallographic sites (the 8-coordinated and 7-coordinated). For Ln = Nd, two phases with the Cmcm and Ccmm space groups coexist at room temperature. When the temperature was increased, the Nd 3 SbO 7 compound transformed into a single phase with the space group Cmcm.Through magnetic susceptibility measurements, an antiferromagnetic transition was observed at 3.0 K (Ln = Nd) and 7.8 K (Ln = Tb). Analysis of the magnetic specific heat for Tb 3 SbO 7 indicates that the 8-coordinated Tb ions magnetically orders at 7.8 K, and with furthermore decreasing temperature, the 7-coordinated Tb ions shows antiferromagnetic ordering at 3.0 K.3

“…Due to this unique crystal structures and possible related magnetic properties, many studies have been performed, especially for the magnetic properties of compounds containing Ru 5+ ion at the M-site because of its largest possible spin (S = 3/2) [3][4][5][6][7][8][9][10][11][12][13].…”

Ternary rare earth antimonates Ln 3 SbO 7 (Ln = rare earths) were prepared and their structures were determined by x-ray diffraction measurements. They crystallize in an orthorhombic superstructure of cubic fluorite (space group Cmcm for Ln = La, Pr, Nd; C222 1 for Ln = Nd ~ Lu), in which Ln 3+ ions occupy two different crystallographic sites (the 8-coordinated and 7-coordinated sites). Their magnetic properties were characterized by magnetic susceptibility and specific heat measurements from 1.8 to 400 K. The Ln 3 SbO 7 (Ln = Nd, Gd -Ho) compounds show an antiferromagnetic transition at 2.2 ~ 3.2 K. Sm 3 SbO 7 and Eu 3 SbO 7 show van Vleck paramagnetism. Measurements of the specific heat down to 0.4 K for Gd 3 SbO 7 and the analysis of the magnetic specific heat indicate that the antiferromagnetic ordering of the 8-coordinated Gd ions occur at 2.6 K, and the 7-coordinated Gd ions order at a furthermore low temperature.3
