Abstract
V-51 NMR experiments have been performed to study the local magnetic and el ectronic properties of the vanadium oxide bronzes beta -AV(6)O(15) (A = Na and Ca). We observed a drastic change in the V-51 NMR spectrum due to a cha rge-ordering transition in both oxides. The ground state of NaV6O15 is foun d to be an antiferromagnetically ordered state, whereas that of CaV6O15 is nonmagnetic. This is closely related with the number density of Vlf ions an d the structure of the charge ordering, (C) 2000 Elsevier Science Ltd. All rights reserved.
