Heavy-Fermions in a Transition-Metal Compound: LiV sub 2 0 sub 4

The recent discovery of heavy-Fermion properties in Lithium Vanadate and the enormous difference in its properties from the properties of Lithium Titanate, as well as of the manganite compounds, raise some puzzling questions about strongly correlated Fermions. These are discussed as well as a solution to the puzzles provided.
