摘要
Bogoliubov de Gennes 方程在铁磁性的超导体 / 绝缘体 / 正常 metal/insulator/ferromagnetic/superconductor (FS/I/N/I/FS ) 被用于连贯效果的学习连接。我们在铁磁性的超导体，温度，和正常金属厚度作为交换地的功能在 FS/I/N/I/FS 计算了 Josephson 水流。在 FS/I/N/I/FS 的 Josephson 批评水流作为正常金属的长度的功能展出摆动，这被发现。交换地总是压制 Josephson 为二铁磁性的超导体(FS ) 的磁性的时刻的一种平行配置的批评当前的 Ip 电极。在反平行的配置，在摆动的最小的价值的 Josephson 批评当前的 IAp 为强壮的障碍力量并且在低温度与交换领域增加。
The Bogoliubov de Gennes equation is applied to the study of coherence effects in the ferromagnetic superconductor/insulator/normal metal/insulator/ferromagnetic/superconductor （FS/I/N/I/FS） junction. We calculated the Josephson current in FS/I/N/I/FS as a function of exchange field in ferromagnetic superconductor, temperature, and normal metal thickness. It is found that the Josephson critical current in FS/I/N/I/FS exhibits oscillations as a function of the length of normal metal. The exchange field always suppresses the Josephson critical current Ip for a parallel configuration of the magnetic moments of two ferromagnetic superconductor （FS） electrodes. In the antiparallel configuration, the Josephson critical current IAv at the minimum values of oscillation increases with the exchange field for strong barrier strength and at low temperatures.
