The electric field gradients created at <sup>111</sup>Cd nuclei by dilute Al, V and Cr impurities in the nickel matrix are studied by the technique of time-differential perturbed angular correlation. The results show conclusively that there exists a strong repulsive interaction between the In probe and the Al, V or Cr impurity atoms. The magnetic hyperfine field satellites due to various probe-impurity configurations originate from a highly non-random distribution of impurities within a 78-atom sphere (five atomic shells in a FCC lattice) around the In probe.
