Abstract
We found a high-frequency dielectric and magnetic anomaly in NaV2O5 at the phase transition into the spin-gap state. The dielectric constant anomaly i s of the antiferroelectric type, which is in agreement with the models assu ming the zigzag charge ordering in the nb-plane. (C) 2000 Elsevier Science B.V.
