Lithium vanadate is unusual among the structures with 3d atoms at magnetic sites in showing behavior characteristic of the heavy fermions. All other systems showing this behaviour are modeled as having localized f-electrons interacting with a sea of conduction electrons (s-electrons). I will review the experimental evidence for the heavy fermion character in this system, and discuss some of the ideas that go into building a microscopic model for this behavior, and some of the properties we expect such a model to possess. Frustration of the magnetic lattice seems to prevent magnetic ordering and allow the system to achieve the heavy fermion state despite begining with a mixture of spin 1 and spin 1/2 on equivalent sites.
