摘要：

Micro Raman scattering was used to study the structural stability of cobalt ferrite-based (CoFe2O4) nanoparticles, under illumination with the 514 nm line, at 7 mW laser power. Different samples were investigated after performing the steps of the magnetic fluid (ME) preparation. Raman spectra of samples peptized at 0.25 mol/l perchloric acid showed features similar to bulk maghemite. However, samples peptized at 0.75 mol/l perchloric acid showed features similar to the Fe3O4 phase. (C) 2004 Elsevier B.V. All rights reserved.
