Interference phenomena in clean Josephson junctions with ferromagnetic bilayers: Spin-triplet correlations and resonances
We study the Josephson effect in planar SF1F2S junctions that consist of conventional s-wave superconductors (S) connected by two metallic monodomain ferromagnets (F1 and F2) with an arbitrary transparency of interfaces. We solve the scattering problem in the clean limit based on the Bogoliubov–de Gennes equation for both spin-singlet and odd in frequency spin-triplet pairing correlations. We calculate numerically the Josephson current-phase relation I(ϕ). While the first harmonic of I(ϕ) is…
