摘要: The isothermal section of the Co-Gd-Sn system between 0 and 55 at.% Sn at 500 °C was investigated by means powder x-ray diffraction. Five ternary phases were identified or confirmed: Gd6Co2Sn, Gd3Co8Sn4, Gd3Co6Sn5, Gd4CoSn8, Gd3Co4Sn13. A new phase Gd117Co57Sn112 with Dy117Co57Sn112-type structure, space group \( Fm\bar{3}m \), lattice parameter a = 3.0023 (4) nm found. rare earth compound Gd3Co8Sn4 presents homogeneity range 20 to 27 along Gd iso-concentration line. Comparison this those reported in literature made differences discussed.
