Abstract

We have investigated the magnetic properties of vanadium oxide nanotubes (VOx -NTs) of various V4+ concentrations. Ferromagnetic response was observed at ∼100 K only in the V4+ -rich water-intercalated VOx -NTs, whose saturation moment is close to that of Li-doped VOx -NTs, a recently-reported room-temperature ferromagnet. The ferromagnetism may have to do with charge localization as well as the spin concentration giving rise to removal of spin frustration according to our previous study.
