title = "Coexistence of Kondo effect and ferromagnetism in the Underscreened Kondo Lattice model",

abstract = "In this work we use a Schrieffer-Wolff transformation in a two-fold degenerate periodic Anderson lattice to describe the coexistence of Kondo effect and ferromagnetism in some uranium and neptunium compounds. We show that the inclusion of a bandwidth for the f electrons can account for a weak delocalization of 5f electrons. Using a mean field approximation, we show that a maximum of TC versus JK can be found when the bandwidth is proportional to JK.",
