  The magnetic properties of Ce in the $\alpha$ and $\gamma$ phase are
calculated within the LDA+DMFT approach. The magnetic susceptibility in these
two phases shows a similar behavior over a wide temperature range: a
Curie-Weiss law at high temperatures, indicating the presence of local moments,
followed by a maximum in a crossover regime, and a saturation characteristic of
a state with screened local moments at low temperature. The difference in
experimentally observable magnetic properties is caused by the shift of the
susceptibility to higher temperatures in the $\alpha-$phase compared to the
$\gamma-$phase, due to the larger hybridization between localized $4f-$states
and conductive $spd-$electrons.
