摘要：

This paper presents new physical properties of nanocrystalline SnFe2O4 ferrites, synthesized by co-precipitation method. Magnetization measurement indicates superparamagnetic behavior; the blocking temperature is about 300 K. We performed X-ray diffraction, infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), Energy Dispersive Spectroscopy (EDS), UV-visible measurement, superconducting quantum interference device (SQUID) and zero-field-cooled (ZFC)/field-cooled (FC) measurements. TEM images show the high crystallinity and grain size of ferrite nanocrystals. The refinement result showed that the type of the cationic distribution over the tetrahedral and octahedral sites in the nanocrystalline lattice is a partially inverse spinel. The obtained UV-vis data were used to calculate the energy band gap (3.82 eV) of nanocrystalline SnFe2O4. On the other hand the magnetic properties of the samples; saturation magnetization (M-s) and coercive field (H-c) were determined using a superconducting quantum interference device (SQUID).
