A coexistence between the Kondo effect and the ferromagnetic order has been observed in some Uranium compounds such as UTe or UCu 0.9 Sb 2 , which order ferromagnetically at roughly 100 K and present a Kondo resistivity decrease above it. Recently we have developed the underscreened Kondo lattice (U
We clarify the nature of the dimerized ground state found in the one-dimensional Kondo lattice model at quarter conduction electron filling. The conduction electrons mediate, through the RKKY mechanism, the long-range interactions among localized spins necessary to induce dimerization in that sub-sy
