| 英文摘要 | fe3si nanoparticles with a size of about 6-9 nm well dispersed on silica have been prepared by pyrolysis of ferrocene-polydimethylsilane composites at 600 degrees c. powder xrd patterns, tem and hrtem images, and xps spectra revealed that the average particle size increased with increasing pyrolysis temperature and a new phase, fe5si3, appeared when the pyrolysis temperature was above 800 degrees c. fe-57 mossbauer spectra, m - h curves and fc and zfc curves demonstrated that the as-prepared nanoparticles presented superparamagnetic behavior at 27 degrees c and ferromagnetic behavior at -268 degrees c, and their particle sizes had a great impact on their magnetic properties. the fe3si nanoparticles on silica may find applications in magnetically recording materials, magnetically separable catalysts and electrode materials for spintronic devices. |
