Abstract
The local susceptibilities beta(T) of isolated Rh impurities in parama gnetic dilute Pt(Fe) alloys have been measured using the TDPAC method. The results show existence of 4d magnetic moment for Rh with reduced spin fluctuation temperatures (T(sf)). It is suggested that moment sta bility scaled by T(sf) is governed mainly by the interatomic d-d excha nge interaction caused by induced ferromagnetic polarization of host d band electrons.
