摘要：
We calculate the dc Josephson current in superconductor/Ferromagnet-insulator-superconductor junctions (S/F-I-S) and the self-consistent equation in ferromagnetic superconductor, within Bogoliubov-de Gennes equation and Furusaki-Tsukada formula. It is shown that the ferromagnetic exchange interaction suppresses the Andreev reflection, and consequently the Josephson current in S/F-I-S strongly depends on the ferromagnetic exchange interaction.
