✦ Synopsis
Quasibinary Laves systems ðCe 12x La x ÞRu 2 and ðCe 12y Ca y ÞRu 2 doped with 111 In were synthesized at a pressure of 8 GPa, and variations of the electric quadrupole interaction of 111 Cd at the Ru sites have been studied by the method of time-differential perturbed angular correlation in a wide range of Ce -La and Ce -Ca relative concentrations. In the first case two sites with quadrupole frequencies n Q ø 220 and 150 MHz persist at x # 0:2; while at x $ 0:3 only the higher frequency component remains in the spectra, which are similar to that of pure LaRu 2 . In the series ðCe 12y Ca y ÞRu 2 ; at y $ 0:03 the lower frequency component was washed out except in samples with y ¼ 0:1 and 0.2, where it was restored.
