PHASE DIAGRAM OF THE FERROMAGNETIC KONDO LATTICE

The ground state properties of the ferromagnetic (FM) Kondo lattice system are discussed by using the self-consistent field approximation. A phase diagram of the system including saturated ferromagnetic and FM-Kondo coexistent phases has been given. The results obtained can be used to explain the experimental observations for the first FM. Kondo lattice material Ce-Si_ξ.
