Resumo
Perturbed angular correlation experiments on 140LaY140Ce probes substituting for the
Gd positions on GdCo2 demonstrate that the magnetic hyperfine field (MHF) on Ce atoms follows
an expected Brillouin function but with a substantially reduced saturation value as compared with
the MHF acting on free Ce+3 ions. The results were interpreted with the aid of first principles
electronic structure calculations showing that the reduced value of the MHF is a consequence of a
small orbital contribution to the MHF which was attributed to the de-localization of the Ce 4f
electronic state.
