Zusammenfassung
Ternary gallides RNi(3-x)Ga(x) (R equivalent to Y, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu) have been investigated by means of Xray phase and structure analyses. The new compounds were all found to be isotypic; in the case of YNi2.5Ga0.5 the structure type was refined from powder diffraction data (CeNi3 type of structure, space group P6(3)/mmc, Z=6, R(I)=0.124). At 600 degrees C all the RNi(3-x)Ga(x) compounds have homogeneity ranges between x=0.12 and 1.00. The electrical properties of the DyNi2.68Ga0.32, HoNi2.2Ga0.8, TmNi2.44Ga0.56 and LuNi2.44Ga0.56 compounds were investigated in the temperature range 77 K<T<363 K. All of them have metallic-type conductivity.
