    Abstract

    We report on magnetic susceptibility, 51V NMR and EPR study of multiwall vanadium oxide-decylamine nanotubes. Our measurements reveal the presence of a diamagnetic V5+ and two paramagnetic V4+ ions, respectively. NMR spectra and magnetic susceptibility data estimate the V4+ ions as ∼31%-35% of the entire vanadium ions content. EPR evidences that the paramagnetic V4+ subsystem consists of ∼10% of individual ions (hyperfine structured polycrystalline pattern) and ∼90% of exchange coupled entities(Lorentzian line).
