The perturbed angular correlation studies of Ag–Zr compounds with 111Cd probes

The electric quadrupole hyperfine interactions for 111Cd probes in polycrystalline ZrAg and Zr2Ag were measured in the wide temperature range. For both samples the two unique quadrupole frequencies νQ with asymmetry parameters η = 0 were observed indicating that 111In/111Cd probe impurities substitute both—Zr and Ag sites in B11 structure of ZrAg and in C11b structure of Zr2Ag phase. The results are compared with our previous experiments on isomorphous Hf–Ag compounds.
