%X 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.
