Abstract: The experimental study of the low temperature (down to 0.4 K) specific heat of the Kondo ferromagnet system Ce1-xYxNi0.8Pt0.2 is presented. Special attention has been paid to the Ce0.8Y0.2Ni0.8Pt0.2 composition, which is situated near the Zero Temperature Phase Transition. This compound presents a marked divergence of the specific heat at low temperatures, signature of a Non Fermi Liquid behaviour. Different frameworks which could account this behaviour are analysed, being the most plausible a “strong coupling” situation with disorder effects. The importance of these effects is discussed in the general scenario of the Non Fermi Liquid compounds considering the differences between “ligand” and “Kondo hole” systems.
