【 摘 要 】

The magnetic properties of Ce in the a and. 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 a phase compared to the. phase.
