| 摘 要： | 考虑粗糙界面散射和自旋翻转,运用Slonczewsik模型,我们研究了铁磁/绝缘体/铁磁中的磁性隧穿,得到自旋电流密度表达式.在界面势垒比较低时,自旋电流受随粗糙界面散射和自旋翻转的强度改变明显.

| Abstract: | Considering the rough-scattering effect and spin-flip effect in the insulator, we investigate the spin current in a ferromagnet/insulator/ferromagnet(FM/I/FM) tunneling junction using Slonczewsik's model.An expression of spin current as a function of barrier height,interface roughness and spin-flip effect is obtained.In lower barrier case,it shows that the spin current is depended on the rough-scattering effect and spin-flip effect. |

| Keywords: | spin current spin-flip effect rough-scattering effect |
