Abstract
We investigate the magnetic field dependence of the spin-Peierls transition in NaV2O5 in the field range 16-30 T. The transition temperature exhibits a very weak variation with the field, suggesting an unusual mechanism for t he formation of the spin-Peierls state. We argue that a charge ordering tra nsition accompanied by singlet: formation is consistent with our observatio ns.
