Resumo
Perturbed γ − γ angular correlation spectroscopy (PAC) has been used
to investigate the hyperfine interactions in the intermetallic compound CePd2Si2
using 111In→111Cd probe nuclei. Samples of CePd2Si2 were prepared by melting
constituent elements in an arc furnace under pure argon atmosphere. Carrier-free
111In nuclei were introduced into the samples by thermal diffusion at 800◦C in
vacuum during 12 h. The measurements were performed in the temperature range
of 4.2–300 K. Above the magnetic transition temperature (TN = 10 K), the results
show two distinct and well defined quadrupole interactions that were assigned to
probe nuclei occupying Ce and Si sites in the compound. The quadrupole frequencies
were found to decrease linearly with increasing temperature. The PAC spectra taken
below 10 K were analyzed with a model including combined electric quadrupole
plus magnetic dipole interactions, from which the hyperfine magnetic field was
determined.
