The Magnetic Response of Europium Implanted in Cerium and in Platinum as Investigated by the PAC-Method

Abstract

The magnetic response of europium in g-cerium and in platinum was studied by applying the perturbed angular correlation spectroscopy. The probe nuclei were 147 Eu(11/2 j ) and 149 Eu(11/2 j ). The response in g-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 multiplet system.
