We introduce a novel mechanism for the unusual itinerant ferromagnetism found in mixed valence systems like Ce(Rh₁₋ₓRuₓ)₃B₂, LaₓCe₁₋ₓRh₃B₂, US, USe, and UTe. With it we can provide an explanation for the long-unexplained large value of Tc (100) value and the maximum in the magnetization below Tc found experimentally. We also show that this novel itinerent ferromagnetism can be continuously connected with the localized case for which the energy scale is much smaller (JRKKY 1).
