The magnetic properties of the ferromagnetic Kondo-lattice model (FKLM) are investigated. Starting from an analysis of the magnon spectrum in the spin-wave regime, we examine the ferromagnetic stability as a function of the occupation of the conduction band n and the strength J of the coupling betwe

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
Kondo compounds exhibit a rich phase diagram, which involves different types of magnetic ordering and superconductivity, depending on temperature, pressure and electron concentration. In the Kondo lattice model, we develop the chain of equations of motion generated by the conduction electron Green's
