| 摘 要： | 对采用磁控溅射制备TbFeCo/Si、Ag/TbFeCo/Si系列薄膜的溅射工艺进行了研究,分析了TbFeCo薄膜的生长机理,并对其光学性质、磁性质和磁光性质进行了分析。实验结果表明,不同压强对TbFeCo薄膜的成分比有明显的影响,确定了工作压强为2.0 Pa是适合的,这时制备的薄膜的成分原子比和靶的原子比最接近。用全自动椭圆偏振光谱仪测量了TbFeCo薄膜在1.5~4.5eV的椭偏光谱,结果表明,随着工作气压、溅射功率和Ar气流量的变化,薄膜的光学性质均发生明显变化。对制备的Ag/TbFeCo/Si和TbFeCo/Si磁光薄膜的磁光性质进行了分析,结果表明,Ag保护膜对TbFeCo磁光薄膜的磁光性质会产生显著影响。
