| 摘 要： | 用一种简单的水热法合成了平均粒径为400nm、厚度为70nm的Fe3O4纳米片，通过XRD、SEM对样品的结构、形貌进行了表征，用超导量子干涉仪（SQUID）对其磁学性能进行了研究，实验结果表明，反应温度、时间、搅拌速度均对产物的形貌产生重要影响。在常温下的磁学性能测量显示，其饱和磁化强度和矫顽力分别为94．60emu·g^-1,101 Oe，磁性能得到了较大改善。

| Abstract: | Nanostructured magnetite plates were synthesized by a simple hydrothermal route. The morphology and structure of magnetite nanoplatelets were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Using superconducting quantum interference device (SQUID),the magnetic properties were studied. The results showed that the as-synthesized sample exhibits plate-like structures. The size and thickness of the plates are estimated to be about 400 nm and 70 nm respectively. The experiment re... |
