We report on the synthesis and crystal structure of the new family of rare earth ternary equiatomic RZnSn compounds. The phases are found to form for R = La to Nd, Sm, Gd to Lu, Y, all belonging to the hexagonal hP12-P63/mmc YPtAs structure type. The lattice parameters, as obtained by the Guinier method on polycrystalline samples, vary...

The synthesis and crystal structure of the new family of rare earth ternary equiatomic RZnGe phases are reported. The compounds are found to form for R = La to Nd, Sm, Gd to Tm, Y, all crystallizing with the hexagonal hP12-P63/mmc YPtAs structure type, a four-layers superstructure derivative of the AlB2 type. No formation of the equiatomic...

Phases YbZn1-xAlx, YbZn2-xAlx and YbZn3-xAlx were studied by electron microprobe analysis and X-ray single crystal and powder methods. The compound YbZn0.8Al0.2 crystallizes with the CsCl-type, a=3.635(2) Å. Four phases were investigated by single crystal X-ray diffraction: YbZn0.996(6)Al1.004(6), MgNi2-type, P63/mmc, a=5.573(1), c=18.051(3) Å,...

Several samples were prepared in the title systems, starting from the elements sealed under argon in Ta crucibles, melting in an induction fornace and annealing at 823 K. Six ternary phases were found: EuCu2Sn 2, a = 11.100 (3), b = 4.307 (1), c = 4.824 (1) , β = 108.88 (1)°, and SrCu2Sn2, a = 11.197 (4), b = 4.322 (2), c = 4.859 (1) , β =...

AC and DC magnetic measurements were performed on the ternary intermetallic phase Tb3Co8Sn4. The compound shows a ferrimagnetic transition at T-c=91 K. From the imaginary part of the AC susceptibility a second broad peak was detected at T-s=28 R and ascribed to a transition to a spin glass state. Zero field cooled (ZFC) and field cooled (FC)...
