| Abstract: | Co40Fe40B20-SiO2 nana-granular films were synthesized by RF magnetron sputtering. Main factors affecting the anisotropy of the nano-granular films were discussed. The anisotropic coupling model was presented to interpret the origin of the strong uniaxial anisotropy for CoFe based granular films. Thus, it can provide references in theory for adjusting electromagnetic characteristics of CoFe based granular films in the microwave frequency range. |
