We conclude that the mechanism responsible for heavy fermion properties in LiV 2O 4 might be somewhat different from the plain Kondo mechanism in conventional 4f and 5f heavy fermion compounds and perhaps the quantum transition might play an adequate role in heavy-ferrnion behaviors in LiV 2O 4. Similarly, LSDA + GGA calculation yields almost the identical result as that in LSDA. In addition to the above LDA calculation, we also found a LSDA solution of LiV 2O 4 that is lower in total energy than that of LDA calculation. It is insufficient to clarify the origin of local moment in LiV 2O 4 from plain LDA calculations. Furthermore, the N( E F) and y cal are 11.1 (states/eV/f.u.) and 26.7 mJ/mol.K 2 determined numerically by LDA calculation, respectively. The band dispersions near Fermi energy display complicated structures. The energy gap between conduction bands and fully occupied oxygen 2p bands is 1.9 eV. The symmetric characteristics of conduction bands are of t 2g in principle. ![]() The results show that the conduction bands in this compound are formed from V 3 d states with a bandwidth of 2.5 eV. The electronic structure of heavy fermion compound LiV 2O 4 has been calculated using a self-consistent full-potential LMTO method. ![]()
