Abstract

We present here a review on three important problems of the Kondo lattice theory. First, the normal Kondo lattice effect has been extensively studied and accounts for many properties of cerium or ytterbium systems. Then, we present here a new theoretical study of the underscreened Kondo lattice problem, which can well account for the ferromagnetic - Kondo coexistence observed in some uranium compounds such as UTe. Finally, we discuss the spin glass-Kondo competition and the resulting phase diagrams showing spin glass, Kondo and magnetically ordered phases observed in disordered heavy fermion cerium alloys such as CeCuxNi1-x alloys.
