Abstract
By studying the perturbed angular correlations of γ-rays emitted during the decay of 181Hf impurities in the Laves phases of PrFe2, DyFe2, and YbFe2, we have investigated the magnetic hyperfine interaction between these compounds and its daughter nucleus 181Ta, and have determined the temperature dependence of the magnetic hyperfine fields. At room temperature we obtained the following values of these magnetic hyperfine fields Bhf:Bhf(PrFe2)=7.6(1) T, Bhf(DyFe2)=15.5(5) T, and Bhf(YbFe2)=18.8(3) T. When taken together with data obtained previously, the results of our experiments show that for Ta nuclei in the RFe2 Laves phases the values of Bhf depend strongly on whether R is a light or a heavy rare-earth element, which allows us to conclude that in these phases the value of the magnetic moment induced at the impurity Ta nuclei depends on the interatomic distance.
