| 摘 要： | 采用溶胶-凝胶旋涂法和H2还原工艺制备了纳米FeCo/Al2O3复合薄膜.利用X射线衍射仪、扫描电子显微镜、原子力显微镜及振动样品磁强计研究了还原温度对薄膜结构、表面形貌和磁性的影响.结果表明,随着还原温度的升高,薄膜中FeCo的晶粒尺寸和晶格常数变大,薄膜的饱和磁化强度(Ms)也同时增大,其矫顽力(Hc)则先增大,后...

| Abstract: | FeCo/Al2O3 nanocomposite films were prepared by the sol-gel spin-coating method and the H2 reduction technique.The effects of reduction temperature on the structure,thickness,surface morphology and magnetic properties of the films were investigated by X-ray diffractometer,scanning electron microscope,atomic force microscope and vibrating sample magnetometer.The results show that the grain size as well as the lattice parameters of FeCo crystal in the films and the saturation magnification(Ms) of the films in... |
