| 英文摘要 | Structural and magnetic characteristics of fe3-xsnxo4 (x < 0.3) nanoparticles synthesized using the precipitation exchange method have been investigated by x-ray diffraction, transmission electron microscope, mossbauer spectra, x-ray photoelectron spectroscopy and magnetization measurement. the mean particle dimension decreases from 8 to 6 nm, the lattice parameters enlarge, the saturation magnetization decreases, as well as the magnetization and the coercive field increase, with increasing tin-content. the paramagnetic property of the specimens indicates that the replacement of fe3+ by sn4+ on the octahedral sites of fe3o4 causes a progressive lowering of the curie temperature and the curie temperatures of the materials are all lower than that of crystallite tin-doped magnetite. this striking debasing is due to the lessening of the grain size. this is the smallest size reported thus far for paramagnetic tin-doped magnetite particles.
