摘要：

Nanocrystalline magnetite thin film was prepared on to fused quartz substrate by sputtering at an rf power of 50 W. X-ray diffraction study showed that the sputtered film was (110) oriented. The stoichiometry in the thin film has been confirmed through a variety of characterization techniques. The room temperature spontaneous magnetization value (4 pi M-s) of the film was 5100 G. This is about 85% of the bulk value. The resistivity of the film showed a sharp change around 120 K, indicative of the Verwey transition.
