  The phase equilibria in the Gd-V-Sn and Er-V-Sn ternary systems were studied at 870 K by means of X-ray and metallographic analyses in the whole concentration range. Both Gd-V-Sn and Er-V-Sn systems are characterized by formation of one ternary compound at investigated temperature, with stoichiometry RV6Sn6 (SmMn6Sn6-type, space group P6/mmm, a = 0.55322(3) nm, c = 0.91949(7) nm for Gd, a = 0.55191(2) nm, c = 0.91869(8) nm for Er). Solubility of the third component in the binary compounds was not observed. Compounds with the SmMn6Sn6-type were also found with Dy, Ho, Tm, and Lu, while YV6Sn6 compound crystallizes in HfFe6Ge6 structure type. All investigated compounds are the first ternary stannides with rare earth elements and vanadium. (C) 2011 Elsevier B. V. All rights reserved.

  The structure and the magnetic properties of the Gd5Sn4 compound have been investigated by means of X-ray diffraction (XRD) and magnetization measurements. Temperature dependent XRD investigation reveals that there is no structural transition around the temperature at which the first-order magnetic transition occurs in this compound, i.e. the compound retains the Sm5Ge4-type structure from 80 K(T-C), which is different from the Gd-5(Si, Ge)(4) system. Based on the Rietveld refinement of the XRD pattern of Gd5Sn4 compound, we show that the unit cell volume exhibits a dip near the Curie temperature, i.e. a negative coefficient of thermal expansion alpha approximate to -1.5 x 10(-4) K-1 from 82 to 90 K and a positive coefficient alpha approximate to 2.2 x 10(-4) K-1 from 90 to 98 K. The coefficient of thermal expansion from 98 to 298 K is only 2.5 x 10(-5) K-1. (C) 2003 Elsevier B.V. All rights reserved.
