Abstract
A simple molecular field model is used to evaluate the average 4f-5d exchange parameter J0 at the Gd site in Gd ferromagnetic intermetallics. Values of J0, deduced from the Curie temperature and from the measured susceptibilities of the isomorphic intermetallics with La or Lu, range between 800 and 1050 cm-1.
