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.
