Abstract

In the framework of Tsukada-Furusaki formula, we calculate dc josephson current at a ferromagnetic superconductor–insulator–ferromagnetic superconductor (FSIFS) junction as function of phase difference between two ferromagnetic superconductors (FSs). We consider identical FSs which are in three different Cooper pairing states: one singlet S wave pairing and two triplet with parallel and anti parallel spins. We find a sinusoidal form for strong barrier strength for above-mention Cooper pairing states while we find a deviation from sinusoidal form for weak barrier strength. Different behaviors of I(ϕ) in terms of FS exchange field can help us distinguish the type of Cooper pairing state at the FSs which is still a controversial issue in low-temperature physics.
