participate in bonding and that this increased
bonding yields the observed smaller lattice con-
stants l71. In order to obtain more information on
Lh'*se 5f sLates we have performed a systematic study
of the electronic structure of these material using
band theory |8]. From these results as well as from
a new analysis of the paramagnon model and a recent
calculation by llrooks and Kelly |') | on the orbital
contribution I mm Itinerant stales, a new interpre-
tation ot tin' magnetic properties of these systems
is given.
