dc.description.abstract | In this study, we have coated tin oxide (SnO2) nanowires with a Cu shell layer via the sputtering method and subsequently investigated the effects of thermal annealing. The annealing-induced changes in morphologies, microstructures, and compositions of the resulting core-shell nanowires were characterized by using scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), and energydispersive X-ray spectroscopy (EDX). The Cu shell layers were agglomerated to form clusters, which were mainly comprised of the Cu2O phase. For the first time, a hysteresis loop indicating weak ferromagnetism was observed from the pure SnO2 nanowires. Both the coercivity and the retentivity in the hysteresis loop were slightly increased by Cu-sputtering, indicating a very slight enhancement of ferromagnetism. Also, the ferromagnetic behavior was significantly enhanced by thermal annealing. We discuss the possible mechanisms of annealing-induced enhancement of ferromagnetism in the SiO2/Cu core-shell nanowires, which include the generation of Cu2O phase, Cu-doping into the SnO2 lattice, and the generation of oxygen vacancies in SnO2 core nanowires. | - |
