摘　　要：采用溶胶-凝胶工艺将Al均匀掺入FeCo/SiO_2复合薄膜中,与Al作为籽层掺杂相比,研究不同的掺杂方式对FeCo(200)择优取向的影响。结果表明,不同的制备方式和Al掺入含量在薄膜中造成的晶格畸变不同引起择优取向变化趋势的不同。Compared with the doping of Al as a seedlayer,Al metals were doped into FeCo/SiO_2 composite films through sol-gel technique to investigate the effect of different doping methods on the FeCo（200）preferred orientation. The results show that various Al concentrations and doping methods produce different lattice distortion in films,leading to different preferred orientation.
