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.
