The magnetic response of europium implanted in cerium and in platinum as investigated by the PAC method

Abstract

The magnetic response of europium in gamma cerium and in platinum was studied by applying the perturbed angular correlation spectroscopy. The probe nuclei were 147Eu 11 2 and 149Eu 11 2 . The response in gamma Ce was determined by the electronic S J 7 2 ground state of divalent Eu. In Pt, on the other hand, Eu is trivalent J 0 ground state . Here the magnetic contributions originate from Van Vleck terms of the whole multiple
