Abstract
Perturbed gamma-gamma angular correlation technique was used to measure the hyperfine interactions in the compound GdNiIn using the 111In→111Cd and 140La→140Ce probe nuclei at the In and Gd sites, respectively. A unique quadrupole frequency with asymmetry parameter ν = 0.78 was observed for 111Cd probe at In sites for the measurements above Curie temperature. Below TC, the spectra for 111Cd show combined magnetic dipole and electric quadrupole interaction. Below 85 K, a unique magnetic interaction is observed at 140Ce. A linear relationship between the saturated magnetic hyperfine field and the magnetic transition temperature was observed for both probes, indicating that the main contribution to the mhf comes from the conduction electron polarization.
