Specific heat and DC magnetization measurements of Li(V1−xCrx)2O4

Specific heat and DC magnetization measurements have been performed on spinel compounds Li(V 1-x Cr x ) 2 O 4 (0≤x≤0.3). It is found that the heavy Fermi liquid-like state seen in LiV 2 O 4 disappears and a spin-glass state is realized for x≥0.1, due to the partially resolved spin frustration geometrically inherent in the V sublattice. Such a feature is analogous to that seen in another 3d heavy fermion compound Y 0.95 Sc 0.05 Mn 2 .
