摘要
Rie report on an inelastic neutron scattering study performed in the spin ladder compound NaV2O5. The dispersion of the magnetic excitations has been studied along the rungs (a*-axis) and legs (b*-axis) in the charge ordered phase. Our results allow us to propose a model for the charge ordering and the magnetic correlations. (C) 2000 Elsevier Science B.V. All rights reserved.
