摘要
通过计算N -S结与F-S结上反射系数 ,发现F -S结上既有电子反射也有空穴反射 ,而N -S结上只有空穴反射。
The author finds that there is not only electronic reflection but also hole reflection at F_S node,while there is only hole reflection at the N_S node by calculating the reflection coefficient at the N_S node and the F_S node. The cause for that is the unsymmetrical spin within the magnet while the spin within normal metal is symmetrical.
