| 英文摘要 | Ni0.65Zn0.35Cu0.1Fe1.9O4 nanoparticles fabricated by a polyvinyl alcohol (PVA) sol-gel process have been investigated by infrared spectra (IR), X-ray diffraction (XRD), transmission electron microscope (TEM) and Mossbauer spectroscopy measurements. The particles annealed at and above 250 degrees C are single phase NiZnCu ferrite with spinel structure. Particles annealed at and above 350 degrees C behave ferri magnetically, while sample annealed at 250 degrees C is simultaneously paramagnetic and ferrimagnetic. In addition, the transition from the paramagnetic to the ferrimagnetic state can be observed in sample annealed at 250 degrees C as the measuring temperature decreases from 260 degrees C to liquid nitrogen temperature. The magnetic properties of NiZnCu ferrite nanoparticles are clearly size-dependent. The saturation magnetization increases with the annealing temperature. The coercivity of NiZnCu ferrite nanoparticles reaches a maximum when the annealing temperature is 550 degrees C. (C) 2006 Elsevier B.V. All rights reserved. |
