The magnetic properties of Ce in the \ensuremathα and \ensuremathγ phase are calculated within the local-density approximation and dynamical mean-field theory (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 \ensuremathα phase compared to the \ensuremathγ phase.
