Abstract

The coexistence of ferromagnetic order and Kondo behavior, that has been experimentally observed in some uranium compounds, is studied in the framework of an underscreened Kondo lattice model within the mean-field approach. For small values of J_K compared to the bandwidth, a ferromagnetically ordered solution is obtained, while for larger values of J_K a Kondo regime occurs with a Kondo temperature larger than the Curie temperature, suggesting a scenario for the coexistence of Kondo effect and ferromagnetic order.
