On the crystal structure and magnetic properties of the ternary rare earth compounds RETSb2 with RE  rare earth and T  Ni, Pd, Cu and Au

Crystal growth, characterization and physical properties of PrNiSb3, NdNiSb3 and SmNiSb3

“…As Ln progresses from Ce to Sm, the Sb-Sb interatomic distances decrease. Perfectly square sheets have been found for the LnT x Sb 2 (T=Mn, Fe, Co, Ni, Cu, Zn, Pt, Pd, Cd, Ag, Au) compounds, where x is usually less than or equal to 1 [16][17][18][19][20][21][22][23]. The Sb-Sb-Sb angles in LnNiSb 3 (Ln=Ce-Nd, Sm) deviate from 901, further indicating distorted Sb nearly square nets.…”

Anisotropic magnetization and transport properties of RAgSb₂ (R=Y, La-Nd, Sm, Gd-Tm)

“…Magnetic and transport measurements have only been performed on a few members of this family and have concentrated on polycrystalline samples with R = Ce (Lakshmi, 1996;Flandorfer, 1996;Muro, 1997;Houshiar, 1995). However, measurements of the magnetic properties of compounds with rare earth elements other than Ce have been on polycrystalline samples for T = Mn, Co, Au, Zn and Cd (Wollesen, 1996), T=Pt, Au, and Pd (Kasaya, 1993), and T = Ni, Pd, Cu, and Au (Sologub, 1994).…”

“…In order to check for any partial occupancies in the RAgSb2 series, which occur in the related RTSb2 phases with T = Mn, Fe, Co, Ni, Cu, Zn, and Cd (Sologub, 1994;Wollesen, 1996;Leithe-Jasper, 1994;Albering, 1996;Cordier, 1985), a single crystal structure determination was performed on GdAgSbz using a Rigaku AFC6R diffractometer with graphite monochromated Mo Ku (1.= 0.71069~) radiation and a 12 kW rotating anode generator. The data were collected at room temperature using the co-2e scan technique to a maximum 26 value of 60.2°.…”

“…Although the RSb2 series with R = Ce, Pr, and Nd is strongly anisotropic and exhibits sharp well-defined metarnagnetic states for the field applied within the ah-plane (Bud'ko 1998), the crystal structure is weakly orthorhombic (Hullinger 1979, Wang 1967, which greatly complicates the analysis of the magnetic structure. In contrast to the RSb2 series of compounds, RAgSbz crystallizes in the simple tetragonal ZrCuSiz structure (P4/nmm, # 129) (Brylak 1995, Flandorfer 1996, Sologub 1994) consisting of Sb-RSb-AgRSb-Sb layers with the R3+in a location with tetragonal point symmetry (4rnm). .…”

Thermoelectric Properties of Ternary Rare-Earth Copper Antimonides LaCu<I><SUB>x</SUB></I>Sb<SUB>2</SUB> (0.9&le;<I>x</I>&le;1.3)

“…1, LnMSb 2 has three types of layers: CuSb 4 tetrahedral block layers, square Sb nets, and an Ln atom layers. [6][7][8][9][10][11][12][13][14][15][16][17][18] Recent studies on the electrical properties of LnMSb 2 (M: Ni, Cu, Pd, Ag, Cd) have shown that these compounds exhibit low electrical resistivity over the temperature range 4-300 K. [17][18][19][20] In CeNiSb 2 and CeAgSb 2 , the Seebeck coefficient ranges from À5 to 15 mVÁK À1 over this temperature range. 19) However, there is little information on the high-temperature electrical properties of these compounds.…”
