Abstract
VN x nanoparticles and nanowires have been prepared by nitrifying V 2O 5 nanoparticles (NP) and nanowires (NW). The V 2O 5 NP and NW were synthesized by a facile hydrothermal method. Magnetic susceptibility (X) and magnetization measurements showed long range superconducting ordering (LRSO) at the temperature of 5.8 K for NW, but there was no observation of LRSO (at least down to 2 K) for the NP sample, which is a much lower temperature than for the corresponding bulk, while both NP and NW showed the absence of long range magnetic ordering, at least down to 2 K. However, X the data showed that both samples possess a high Pauli-like component, X 0, in their susceptibility (X 0 ≈ 2.22 Ã 10 -4emu/mol for NP and 5 Ã 10 -4emu/mol for NW). Moreover, for the NW samples, X has a strong magnetic field dependence and presents a non-linear field-polarization feature, suggesting strong spin-orbit coupling.
