【摘要】 用直流磁控溅射法制备出Ag/TbFeCo/Si(100)磁光薄膜。利用可变入射角椭圆偏振光谱仪测量了其可见光区的光学常数,给出薄膜介电函数实部和虚部随入射光子能量的变化规律,结果与经典的Drude模型相一致。同时把Ag/Si、Ag/TbFeCo/Si和TbFeCo/Si的光谱进行了比较,结果表明,由于Ag的高反射率,Ag/TbFeCo/Si的光谱更接近Ag。更多还原

【Abstract】 Ag/TbFeCo/Si(100) magneto-optical films were prepared by DC-magnetron sputtering. The dielectric constants of the Ag/TbFeCo/Si were measured by alterable angle ellipsometry. The results are consistent to Drude model. Besides, we compared the spectrum of Ag/Si Ag/TbFeCo/Si and TbFeCo/Si. The results of experiment indicated that the spectrum of Ag/TbFeCo/Si is much more close to that of Ag for its high reflectivity.更多还原
