摘要：

We claim that the observed large reduction of the effective moment and the drastic violation of the Curie-Weiss law in Na2V3O7 (Phys. Rev. Lett. 90 (2003) 167202) is caused by conventional crystal-field interactions and the intra-atomic spin-orbit coupling of the V4+ ion. According to the Quantum Atomistic Solid-State Theory (QUASST) Na2V3O7 is expected to exhibit pronounced heavy-fermion phenomena at low temperatures related to the Quantum Critical Point.
